boxes {simba} | R Documentation |
Uses boxplot
to produce a boxplot, which is then annotated with the number of obbservations in each group. Does allow for more flexibility compared to boxplot.n
. Default size of the text is bigger and per default the numbers are not plotted directly on the x-axis and their distance from the axis can be changed.
boxes(..., top = FALSE, shrink = 1, textcolor = NULL, yadj = NULL)

Parameters passed to boxplot . |
top |
Should the numbers of observations be printed below or above the boxes? Defaults to below (top = FALSE). |
shrink |
Parameter to scale the size of the numbers of observations. Above 1 increases size, below 1 until 0 decreases size. |
textcolor |
Color of the text. Defaults to NULL which than uses the actual plotting colour of the graphics device. |
yadj |
Can be used to adjust the vertical plotting positions of the numbers of observations. Defaults to NULL - no adjustment. |

data(abis) ## see environmental data (see documentation on data for details) abis.env ## calculate the difference in similarities for the three major ## vegetation types ## therefore created a vector from the data expressing belonging ## to the vegetation types: tcs.sub <- rep(0, 61) tcs.sub[abis.env[,29]==1] <- 1 tcs.sub[abis.env[,30]==1] <- 2 tcs.sub[abis.env[,31]==1] <- 3 ## calculate similarity (Jaccard) between all pairs of plots abis.jacc <- sim(abis.spec, method="jaccard") ## make boxplots regarding the similarities for each vegetation ## type, including the number of pairs contained in each box. boxes(as.matrix(abis.jacc)~tcs.sub, shrink=1.2) ## prettier boxes(as.matrix(abis.jacc)~tcs.sub, notch=TRUE, col="grey50", shrink=1.2, ylim=c(-0.1, 0.9))
