Usage
histGroup(data, groups, main = paste("Histogram of", dataname), xlab =
dataname, ylab, col = NULL, alpha = 0.5,breaks = "Sturges",
legend=TRUE,legend.x=80,legend.y=80,legend.pch=15,freq=TRUE)
Arguments
data
vector containing data.
main,xlab,ylab
these arguments to title have useful defaults here.
col
vector containing color for each group. If NULL, the function
"rainbow" is called.
alpha
numeric between 0 and 1. Sets the transparency of the colors
breaks
one of:
- a vector giving the breakpoints between histogram cells,
- a single number giving the number of cells for the histogram,
- a character string naming an algorithm to compute the
number of cells (seeDetails
legend
logical: if TRUE, a legend is plotted
legend.x
x position of the legend from the upper left corner
legend.y
y position of the legend from the upper left corners
legend.pch
integer: define the symbol to visualise group colors (points
) freq
logical: if TRUE, the histogram graphic is a representation
of frequencies, the counts component of the result; if FALSE,
probability densities are plotted for each group.
