Hi, I'm having some problems with a bubble plot (ps package). I don't want tick marks on all four sides (just two), I want to have a smaller font size, and I would like to be able to define bubble sizes shown in the legend (now it shows 0, 0, 0, 9.747 and 4265.757 which is not really convenient. Passing some of the standard plot arguments didn't help (in fact, nothing changed).

The data structures in R are still very puzzling to me. Can anyone tell me how I can easily convert these two dataframes to one single dataframe with two columns (mean and sd) with 7 rows? > meanprofile V1 V2 V3 V4 V5 V6 V7 2292.001 2178.620 1654.310 1784.004 1160.052 1142.061 1046.675 > sdprofile V1 V2 V3 V4 V5

Hi, I have a small set of data on which I have tried some normality tests. When I make a histogram of the data the distribution doesn't seem to be normal at all (rather lognormal), but still no matter what test I use (Shapiro, Anderson-Darling,...) it returns a very small p value (which as far as I know means that the distribution is normal). Am I doing something wrong here? Thanks Pieter

Hi, I'm trying to visualise a matrix using image(), and I would like to add the row and column names as tick labels. I tried adding an axis, but the problem is that this axis goes from 0 to 1 which results in labels being added starting at the far right end of the axis. image(t(data), col = terrain.colors(20), axes=FALSE) axis(3, at = 1:length(colnames(data)), labels=colnames(data)) How
