[R] [FORGED] change text size on a graphics

[carol white]

Hi,I use hist.
If I usehist.result = hist(c(14,20,9,31,17), plot = F)plot(hist.result, labels = T, cex = 2) 
#doesn't increase the font size of all text on the plot: axis annotation, axis labels, count labels on top of the bars 

plot(hist.result, labels = T, cex.axis = 2, cex.label = 2, cex.main = 2) 
# how to increase the size of count labels that are displayed on the top of the bars by labels = T?
 Regards,

 Hi Carol,
If you are using the "barlabels" function in the plotrix package, just
add the usual "cex" argument to the call. Using the first example in
the help page:

heights<-c(14,20,9,31,17)
barpos<-barplot(heights,main="A redundant bar plot")
barlabels(barpos,heights+1,prop=1,cex=1.5)

Jim
