[R] Histogram with logarithmic scale
As I thought, my question was not very interesting. I have now found a solution. The problem, which I think I had not explained clearly, was that I had values >=0 and I wanted to plot an histogram of log(values+1) but with the initial axis, (not the logarithmic). These are the commands I used: ff_function(x) { log(x+1) } data2_sapply(data,FUN="ff") histo_hist(data2) bornes_histo$mids+(histo$mids[2]-histo$mids[1])/2 ax_round(exp(bornes)-1,2) axis(3,bornes,labels=ax) This is OK for me. -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- r-help mailing list -- Read http://www.ci.tuwien.ac.at/~hornik/R/R-FAQ.html Send "info", "help", or "[un]subscribe" (in the "body", not the subject !)
