Question

I could not manage to remove the y axis labels from a conditional density plot (cdplot{graphics}) in order to rotate them horizontally later; axes = FALSE seems not to work. Any idea?
Thanks!

Using the example data from R documentation:

fail <- factor(c(2, 2, 2, 2, 1, 1, 1, 1, 1, 1, 2, 1, 2, 1, 1, 1, 1, 2, 1, 1, 1, 1, 1),
               levels = 1:2, labels = c("no", "yes"))
temperature <- c(53, 57, 58, 63, 66, 67, 67, 67, 68, 69, 70, 70, 70, 70, 72, 73, 75, 75, 76, 76, 78, 79, 81)
cdplot(fail ~ temperature, axes = FALSE)

Warning messages:
1: In density.default(x, bw = bw, n = n, ...) :
  non-matched further arguments are disregarded
2: In density.default(x[y %in% levels(y)[seq_len(i)]], bw = dx$bw,  :
  non-matched further arguments are disregarded

Since you are not giving us any data, I’m using the data provided in example(spineplot).

You can get rid of the axis labels by setting the appropriate parameter to NA:

spineplot(fail~temperature,yaxlabels=NA)

But if you want to orient them horizontally, you normally set las=1. Unfortunately, spineplot doesn’t seem to pass this on, so you need to do a call to par first:

par(las=1)
spineplot(fail~temperature)
