[R] Problem building up ggplot graph in a loop.

Folks, I want to automate some graphing using ggplot. Here is my code graphChargeOffs2-function(coffs) { ggplot(coffs, aes(levels)) dataNames-names(coffs)[!names(coffs) == levels] for(i in dataNames) { thisData-coffs[[i]] last_plot() + geom_line(aes(y = thisData, colour = i)) }

It's been a long time since this topic was posted, but I recently had occasion to use stats::reshape again. This time, I looked closer at the code for the function so I could understand what was going on. I now realize that if the argument varying is a vector of names (as I had) rather than a

Re: [R] Problem building up ggplot graph in a loop.

ggplot is looking for thisData as a column of coffs. the most 'ggplotesque' way of doing this would be: # melt your data to a long format: coffs.melt - melt(coffs, id.vars = 'levels') # plot using colour aes parameter: ggplot(coffs.melt, aes(x=levels, y=value, colour=variable)) + geom_line() +
