Dear R users, I am trying to write myself a loop in order to produce a set of 20 length frequency plots each pertaining to a factor level. I would like each of these plots to be available on the same figure, so I have used par(mfrow = c(4, 5)). However, when I run my loop below, it produces 20 plots for each factor level and only displays the last factor levels LF plots. I'm fairly new to loops in R, so any help would be greatly appreciated.
I have provided an example data set below if required with just 4 factors and adjusted par settings accordingly. Factor <- rep(factor(letters[1:4]), each = 10) Size <- runif(40) * 100 par(mfrow = c(2, 2)) for (i in Factor) { LFchart <- hist(Size[Factor == i], main = i, xlab = c("n =",length(Size[Factor == i])), ylab = "") } P.S. Also just a quick annoying question. My xlab displays: n = 120 I would like it to display: n = 120 but just cant get it to work. Any thoughts.
