Hi there, I guess this must be a standard issue, but I'm starting to go crazy with it. I simply want a plot with the x axis being logarithmic, having labels 1, 10, 100..., and ten unlabelled ticks between each of them - just as they introduce logarithmic axis at school. I've played around a bit with log="x", xlog=T (where exactly is the difference here?), xaxp, and xaxt (unfortunately xaxt="l" isn't implemented). The best I get is a plot with an axis having a single 100 and nothing else...
here is what I've tried: pdf(file="kennlinien.pdf"); par(log="x", xlog=TRUE); kennlinie1 <- c(8.0746909, 3.9916973, 9.9789444, 19.962869); kennlinie2 <- c(6.0994206, 8.9661081, 19.924883, 31.879496); reizstaerke <- c(76, 92, 108, 124); #plot(reizstaerke, kennlinie1, ylim=c(0, max(kennlinie1, kennlinie2)), xlim=c(0, max(reizstaerke)), log="x", xlog=TRUE, xaxp=c(1, 2, 1), type="b"); #plot(reizstaerke, kennlinie1, type="b", log="x", xlog=TRUE, xaxp=c(1, 2, 3)); plot(reizstaerke, kennlinie1, type="b",usr=c(min(reizstaerke), max(reizstaerke), min(kennlinie1, kennlinie2), max(kennlinie1, kennlinie2)), log="x", xlog=TRUE, xaxp=c(1, 2, 3)); #points(reizstaerke, kennlinie2, xlog=TRUE, xaxp=c(1, 3, 3), type="b"); dev.off(); Certainly I've missed something, but I can't figure it out.
