...But when I generate the boxplot with ylim=c(1, max(dat)) it doesn't properly generate the whiskers or beginning of the boxes, because some of the mins and first quantiles are 0. Can anybody help and tell me how I can generate a logarithmic y scale starting at 0? Thanks in advance, -- Anne Skoeries [[alternative HTML version deleted]]

Hello, how can I get a variable driven summary of one column of my data.frame? Usually I would do > summary(data$columnname) to get a summary of column named "columnname" of my data.frame named "data". In my case the columnname is not static but can be set dynamically.

Hello Everyone,   Learning about R and its wonderful array of functions. If it's not obvious, I usually try to find out what a function stands for.

To do some calculations on such big matrices R just needs too much memory for my PC (4GB installed). So I need a solution to work with large datasets. I'm trying to use the ff-package but I don't think I really understand the whole functionality of the
