R help - Jan 2012 - plot with ylim with regural interval

Dear Researchers,

sorry for the easy question but Is it possible to plot with an interval of
1 or .5 in a plot using ylim?

Thanks
gianni

x = 0:10;
y = 0:10;

plot(x~y,ylim=c(0,10),las=1)

Hi Gianni,

Yes, take a look at

x <- y <- 1:10
plot(x, y, ylim=c(0,10),las=1, yaxt = 'n')
axis(2, seq(0, 10, by = .5), seq(0, 10, by = .5), las = 2)

plot(x, y, ylim=c(0,10),las=1, yaxt = 'n')
axis(2, seq(0, 10, by = 1), seq(0, 10, by = 1), las = 2)

Also, check ?plot and ?par for more details.

HTH,
Jorge.-

plot(x~y,ylim=c(0,10), xaxt="n")
axis(1, at=seq(0, 10, by=0.5) , labels= seq(0, 10, by=0.5),  
cex.axis=0.75)

Unless you make the cex.axis number small enough, axis() won't put  
them all in.
