arrange multiple graphs using a for loop in ggplot2

Question

I want to produce a pdf which shows multiple graphs, one for each NetworkTrackingPixelId. I have a data frame similar to this:

> head(data)
  Net         


        

Answer 1

I think you would be better off writing a function for plotting, then using lapply for every Network Tracking Pixel.

For example, your function might look like:

    plot.function <- function(ntpid){
    sub = subset(dataset, dataset$networktrackingpixelid == ntpid)
    ggobj = ggplot(data=sub, aes(...)) + geom...
    ggsave(filename=sprintf("%s.pdf", ntpid))
    }

It would be helpful for you to put a reproducible example, but I hope this works! Not sure about the vector issue though..

Cheers!
