aggregate months to years
...t would show me the FREQ per year and not per month? barplot(as.vector(ex)) # Sorry for the bad example, of course my data.frame is much bigger and the barplot gives me a nice monthly time series of events, but I really only want the occurrences per year, not per month. Grateful for your advice! Friderike

'for' loop, two variables
...;46 & x<52 & y<12) 1 else 0 } res <-NULL for (i in 40:60 & j in 0:20) res <-c(res,fn(i,j)) # How do I have to write the expression "i in 40:60 & j in 0:20"? Or is there no way to do that, i.e. I have to do the calculation in two steps? Thanks in advance! Friderike [[alternative HTML version deleted]]
