Generate many plots at once in R

I have a function which generates a plot: function(x, y,"name")

I would like to generate as many plots as "names" present in character z

z

[1] "Bzw1"          "Dnajc1"        "Ppig"          "Prex1"         "Dpm1"          "Prpf38b"      
[7] "Snrnp70"       "Spty2d1"       "Cbl"           "Anxa2"         "Ggnbp2"        "Cltc"

and save all of them in a working directory.

Voted for above answer. However this is one particular place where a for loop is not a bad choice either. As in:

z <- c("Bronx","Staten","Tribeca")
func <- function(i,z){

  filename <- paste0("plot_",i,".png")
  png(filename)
  plot(1:30,rep(which(i==z),30)) # just getting 3 simple plots to print
  dev.off()}

for (i in z) func(i,z)
# You will find the plots as .png files in your working directory 
# with "plot_" prepended to each name

Suppose your function is custom_plot. Then, try with this:

lapply(X = z,
       FUN = function(name)
       {
           png(filename = paste0(name, ".png"))
           custom_plot(x, y, name)
           dev.off()
       })
