number precision
Hi, I'm trying to find a way to determine how many digits a number has. I tried using nchar(paste(number)), but unfortunately paste will reduce 8.00 to "8". Any thoughts?

barplot problem
...ween the names (which I have rotated using las=1) and the label. I have been fiddling with the graphical parameters but nothing seems to work. Maybe a graphical representation of the graphical parameters would be helpful (cf the CSS box model). Thanks!

bubble plot problems
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).

how to automatically maximize the graph window (under XP) ?
Hello, I'm trying to produce graphs automatically from data stored in database. Before saving the graphs, I would like to maximize the size of the graphs. The best would be to directly open maximized windows with x11() but up to now I failed doing it. I tried different widths and heighs but I never managed to obtain a full screen window. Is there a command to do it ? Thanks in advance, Ptit

dataframe conversion
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

normality test
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

custom tick labels on image
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
