axis() default values for "lty", "lwd", and "col"
I believe this to be deliberate. If I do par(lty=2,lwd=3,col="blue") plot(1:10) I do not want the axes to be thick, dotted and blue, with black labels. (It is also I suspect deliberate that plot(1:10,lty=2,lwd=3,col="blue") does not pass any of those parameters on to axis().) You say you made the labels bigger: to do that you needed to set cex.axis and cex.main, not cex. I'm afraid this change would break a lot of existing code. I am aware that S-PLUS does this (with blue labels too), and I have always found it irritating to have to work around it.

I would like to recommend a minor modification in axis() which I believe
can simplify the making of plots for publications. I am trying to define
default values for par() in order to make labels bigger and lines thicker,
so that the resulting plots look good when resized for publication
purposes. I ran into the following problem...
axis() does not use par() values as default for "lty", "lwd", and "col".
Here is an example.
par(lty=2,lwd=3,col="blue")
plot(1,1,bty="n",axes=F)
axis(1)
axis(2)
Because axis() doesn't use the par() values, I have to explicitely define
the parameters "lty", "lwd", and "col" in my axis() calls. It would make
sense if axis() used the par() values by default.
Hence, I recommend this simple fix in the axis() function([...]) statement
in order to have axis() read the par() values for "lty", "lwd", and "col".
axis <-
function (side, at = NULL, labels = TRUE, tick = TRUE, line = NA,
pos = NA, outer = FALSE, font = NA, vfont = NULL, lty = par("lty"),
lwd = par("lwd"), col = par("col"), ...)
{ [...] }
I use R1.7.0 on Red Hat Linux 7.2.
