Warning message:
In matplot(x, y, type = "l") :
default 'pch' is smaller than number of columns and hence recycled
Why is it complaining if I specifically ask for type="l", so no pch
involved?
Annoyance or feature?
Perhaps annoyance, if you like to be annoyed ... or just a warning that
can be ignored since no pch is involved.
The fix (if needed) is simple. In the matplot code change:
if (is.null(pch)) {
to:
if (is.null(pch) & (type[1] %in% c('p','b','o'))) {
Thanks, you meant && rather than &, I suppose.
