Dear all, I've come across a problem using strptime, can anyone explain what's going on? I'm using version 2.7.0 on Windows XP.

...(levels(factor(ID))) for (i in 1:length(patients)) { max.cycle[i] <- max(cycle.number[(ID %in% patients[i] )]) } But i would like to know if there is a better or more elegant way of pulling out the maximum cycle.number for each ID? Perhaps without the need for using a for loop? Many thanks, Caroline [[alternative HTML version deleted]]

...my data using the ward-method. In several papers I read (e.g. Bahrenberg) that it is neccesary to use the "squared euclidean distance" with the ward-method. Unfortunatelly I cannot find this term in r as a method for measuring the distance. Does anybody have an idea? Thanks in advance, Carolin [[alternative HTML version deleted]]

I would like to create one large plot that contains 5 different sections, each with a scatter plot. To clarify, I have divided the countries into 5 groups. For each group (continent), I would like to have the name of the continent on the x-axis, and
