I don't know exactly how partimage

I'd like to use lattice to make graphics under conditional structure like : if (TRUE) { barchart(....) dev.print(png, file = "image1.png", width = 600) } but there's nothing in the output file.

Hi, if you look at the first image (Image1) you see that there are 2 main clusters 7 and 8 I wanted to use pvclust to calculate a p-value whether these clusters are due to chance or statistically significant. Unfortunately pvclust does not provide a p-value for the first brunch (7 and 8). So I added a row to my matrix which is very different to the rest of the data to create an additional

Hello all, I'm trying to group several consecutives rows (and assigning them the same value) while leaving some of the rows empty (when a certain condition is not fulfilled).
