How to edit R plots generated by other function that uses plot to create it?

Question

I'm using the EFACompData from the package RGenData , which can create a plot. However, I want to remove the frame from that plot. How can I do it? The function EFACompData does not have an option to do it.

x <- matrix(nrow = 200, ncol = 9)
for (i in 1:3) {
  shared <- rchisq(200, 1)
  for (j in 1:3) {
    x[, (i - 1) * 3 + j] <- shared + rchisq(200, 1)
  }
}

EFACompData(x, f.max = 5,graph = T)

Answer 1

Since EFACompData uses base graphics, you could try modifying graphical parameters via suitable par settings prior to calling the plot function. For example,

par(bty = "n")
EFACompData(x, f.max = 5, graph = TRUE)

will suppress the box surrounding the plot region. Of course, this only works if the plot function doesn't modify the parameter itself. For EFACompData it works. See help("par") for further graphical parameters.

Note that subsequent "editing" of base graphics is limited to adding things to the current plot via low-level plotting commands such as points , lines , text , title , or legend .
