plot - Rename factors in a spineplot with R -

-

is possible rename factor's in spineplot? names of factors long, overlap.

thanks advices!

reading spineplot, clear can pass parameters yaxlabels , xaxlabels control vectors annotation of axes.

one useful function abbreviate shorten character strings.

combining information spineplot example gives:

treatment <- factor(rep(c(1, 2), c(43, 41)), levels = c(1, 2),     labels = c("placebo", "treated")) improved <- factor(rep(c(1, 2, 3, 1, 2, 3), c(29, 7, 7, 13, 7, 21)),     levels = c(1, 2, 3),     labels = c("none", "some", "marked"))  spineplot(improved ~ treatment, yaxlabels=abbreviate(levels(improved), 2))

enter image description here

not of plot functions in r have type of parameter. more general solution, might necessary rename factors before passing plot function. can access , modify factor names using levels function:

levels(treatment) <- abbreviate(levels(treatment), 5) plot(improved ~ treatment)
