Splitting Y-axis in bar plot - R

Question

How can i split my y-axis in bar plot while plotting in R.

Sample data:

   Name     Freq
  PRIM2      310
 NBPF20       45
  NBPF1       12
   CD24       11
 SEC22B        7
 ZNF718        7

The code I am using to plot this:

d <- read.table("Sample.txt", header=TRUE)
barplot(d$Freq, names.arg=d$Name, col='red', cex.axis=0.8, cex.names=0.7, las=3)

Thank you

The problem is one of the parameters used for plotting is 310 while the other are around 50. So if I can clip/split the y-axis from 100 to 300, I can have a nice graph in place. — Angelo, Sep 11 '14 at 10:02

df <- data.frame(
  Name=c("PRIM2", "NBPF20", "NBPF1", "CD24", "SEC22B", "ZNF718"),
  Freq=c(310, 45, 12, 11, 7, 7)
  )

library("plotrix")
gap.barplot(df$Freq, c(50,300), df$Name)
