Question

I am making a very simple plot in R and would like the change the font size on the y-axis (the years). I have used all the cex. commands, and can change everything except these years.

Here is my matrix (inputm):

     2010  2011
CC 0.5550 0.480
P  3.6700 3.865
PF 1.4625 1.685

And my code:

barplot(inputm,beside=T, horiz=TRUE, xlim=c(-7,7), 
col=c("black","blue","red"), xlab="Mg C/ha", cex.axis=2)

I can get the x-axis labels to change, but not the y. What am I missing here?

Answer 1

Use cex.names as in

barplot(VADeaths, horiz=TRUE, cex.names=0.85)

Which produces
