R help - Jun 2010 - minor tick marks

Hi !

I need a plot for data extending over several orders of magnitude on the y axis.
The following command generates a nice looking semi-log plot for my data:
plot(x,y,log="y",type="l",lty=3,
ylim=c(0.01,2),yaxp=c(0.01,1,1),las=1)

 I would appreciate having also minor tick marks in-between the 3 major ticks
obtained with the above command. The "minor.tick" function in library
Hmisc gives an error when applied to log axes.

Any solution ?

Stéphane

Hello,

Perhaps something like:

 > axis( 2, 0:10/10, las = 1, tcl = -.2 )
