[R] tick marks on fold change versus fold change plot
Dear R users, i try to produce the fold change versus fold change plot where i have the values for x and y ranging from 0.01 to 100. So i start with plot(x,y,xlim=c(0.01,100),ylim=c(0.01,100), axes=F). Then i would like both axes to have tick marks as c(0.01,0.1,1,10,100) but they should appear equidistant.
