## Help Pages

addInterval | Draw intervals or arrows on plots.
add_bars | Adding bars to an existing plot.
add_n_points | Add groups of points to a plot
alpha | Adjusting the transparency of colors.
alphaPalette | Manipulate the transparency in a palette.
axesLabels | Format axes labels.
check_normaldist | Compare distribution of data with normal distribution.
color_contour | Creates a contour plot with colored background.
convertFile | Replacing separators (for example, decimal and thousand separators).
dotplot_error | Utility function
drawDevArrows | Draw arrows between different plots.
emptyPlot | Utility function
errorBars | Add error bars to a plot.
fill_area | Utility function
findAbsMin | Return the value (or the element with the value) closest to zero.
find_n_neighbors | Return n neighbors around given indices.
firstLetterCap | Capitalize first letter of a string.
getArrowPos | Converts coordinates in current plot region to device positions (in inch).
getCoords | Convert proportions into coordinates of the plot or figure region.
getDec | Return the number of decimal places.
getFigCoords | Get the figure region as coordinates of the current plot region, or as corrdinates of the figure region.
getProps | Transform coordinates into proportions of the figure or plot region.
getRange | Function for rounding and/or segmenting a range.
getRatioCoords | Move a vector n elements forward or backward.
get_palette | Retrieve the color scheme for contour plots.
gradientLegend | Add a gradient legend to a plot.
group_sort | Sort split by grouping predictor.
img | Image object.
inch2coords | Convert device position (inch) to coordinates in current plot region.
isColor | Check whether color specifications exists.
keepFigRatio | Calculate the height or width in plot coordinates to keep a given ratio relative to the figure.
legend_margin | Add legend with respect to figure instead of plot region. Allows to move legend to margin of plot.

se | Calculate standard error of the mean.
sortBoxplot | Produce box-and-whisker plot(s) ordered by function such as mean or median.
sortGroups | Sort groups based on a function such as mean value or deviation.
