all line elements (element_line())

all rectangular elements (element_rect())

all text elements (element_text())

all title elements: plot, axes, legends (element_text();inherits from text)

aspect ratio of the panel

labels of axes (element_text()). Specify all axes' labels (axis.title),labels by plane (using axis.title.x or axis.title.y), or individuallyfor each axis (using axis.title.x.bottom, axis.title.x.top,axis.title.y.left, axis.title.y.right). axis.title.*.* inherits fromaxis.title.* which inherits from axis.title, which in turn inheritsfrom text

tick labels along axes (element_text()). Specify all axis tick labels (axis.text),tick labels by plane (using axis.text.x or axis.text.y), or individuallyfor each axis (using axis.text.x.bottom, axis.text.x.top,axis.text.y.left, axis.text.y.right). axis.text.*.* inherits fromaxis.text.* which inherits from axis.text, which in turn inheritsfrom text

tick marks along axes (element_line()). Specify all tick marks (axis.ticks),ticks by plane (using axis.ticks.x or axis.ticks.y), or individuallyfor each axis (using axis.ticks.x.bottom, axis.ticks.x.top,axis.ticks.y.left, axis.ticks.y.right). axis.ticks.*.* inherits fromaxis.ticks.* which inherits from axis.ticks, which in turn inheritsfrom line

length of tick marks (unit)

lines along axes (element_line()). Specify lines along all axes (axis.line),lines for each plane (using axis.line.x or axis.line.y), or individuallyfor each axis (using axis.line.x.bottom, axis.line.x.top,axis.line.y.left, axis.line.y.right). axis.line.*.* inherits fromaxis.line.* which inherits from axis.line, which in turn inheritsfrom line

background of legend (element_rect(); inheritsfrom rect)

the margin around each legend (margin())

the spacing between legends (unit). legend.spacing.x & legend.spacing.yinherit from legend.spacing or can be specified separately

background underneath legend keys (element_rect();inherits from rect)

size of legend keys (unit); key background height & width inherit fromlegend.key.size or can be specified separately

legend item labels (element_text(); inherits fromtext)

alignment of legend labels (number from 0 (left) to1 (right))

title of legend (element_text(); inherits fromtitle)

alignment of legend title (number from 0 (left) to1 (right))

the position of legends ('none', 'left', 'right','bottom', 'top', or two-element numeric vector)

layout of items in legends ('horizontal' or'vertical')

anchor point for positioning legend inside plot('center' or two-element numeric vector) or the justification according tothe plot area when positioned outside the plot

arrangement of multiple legends ('horizontal' or'vertical')

justification of each legend within the overallbounding box, when there are multiple legends ('top', 'bottom', 'left', or'right')

margins around the full legend area, as specifiedusing margin()

background of legend area (element_rect();inherits from rect)

The spacing between the plotting area and thelegend box (unit)

background of plotting area, drawn underneath plot(element_rect(); inherits from rect)

border around plotting area, drawn on top of plot so thatit covers tick marks and grid lines. This should be used withfill = NA(element_rect(); inherits from rect)

spacing between facetpanels (unit). panel.spacing.x & panel.spacing.y inherit from panel.spacingor can be specified separately.

grid lines (element_line()). Specify major grid lines,or minor grid lines separately (using panel.grid.major or panel.grid.minor)or individually for each axis (using panel.grid.major.x, panel.grid.minor.x,panel.grid.major.y, panel.grid.minor.y). Y axis grid lines are horizontaland x axis grid lines are vertical. panel.grid.*.* inherits frompanel.grid.* which inherits from panel.grid, which in turn inheritsfrom line

option to place the panel (background, gridlines) overthe data layers (logical). Usually used with a transparent or blankpanel.background.

background of the entire plot (element_rect();inherits from rect)

plot title (text appearance) (element_text(); inheritsfrom title) left-aligned by default

Alignment of the plot title/subtitleand caption. The setting for plot.title.position applies to boththe title and the subtitle. A value of 'panel' (the default) means thattitles and/or caption are aligned to the plot panels. A value of 'plot' meansthat titles and/or caption are aligned to the entire plot (minus any spacefor margins and plot tag).

plot subtitle (text appearance) (element_text();inherits from title) left-aligned by default

caption below the plot (text appearance)(element_text(); inherits from title) right-aligned by default

upper-left label to identify a plot (text appearance)(element_text(); inherits from title) left-aligned by default

The position of the tag as a string ('topleft','top', 'topright', 'left', 'right', 'bottomleft', 'bottom', 'bottomright)or a coordinate. If a string, extra space will be added to accommodate thetag.

margin around entire plot (unit with the sizes ofthe top, right, bottom, and left margins)

background of facet labels (element_rect();inherits from rect). Horizontal facet background (strip.background.x)& vertical facet background (strip.background.y) inherit fromstrip.background or can be specified separately

placement of strip with respect to axes,either 'inside' or 'outside'. Only important when axes and strips areon the same side of the plot.

facet labels (element_text();inherits from text). Horizontal facet labels (strip.text.x) & verticalfacet labels (strip.text.y) inherit from strip.text or can be specifiedseparately

space between strips and axes when strips areswitched (unit)

space between strips and axes when strips areswitched (unit)

additional element specifications not part of base ggplot2. In general,these should also be defined in the element tree argument.

set this to TRUE if this is a complete theme, such asthe one returned by theme_grey(). Complete themes behavedifferently when added to a ggplot object. Also, when settingcomplete = TRUE all elements will be set to inherit from blankelements.

TRUE to run validate_element(), FALSE to bypass checks.
