[R] How to increase lenght of axis according input data?

[Manish Gupta]

Hi,

I am working on barplot.  I need to plot x-axis but scale on x axis is very
upto 15 while my data is upto 19.

pdf("image.pdf", width=10 , height =13)
par(mar=c(5,22.5,2,2))
barplot(t(data[,2:3]),   beside=TRUE, col=c(rgb(.537, .769, .933),rgb(.059,
.412, .659)), width = 1, horiz=TRUE,cex.names=.9, border ="white",las=1,
cex.axis= 1, cex.lab=1.2)
legend("topright", c("X","Y"), cex=1.5, bty="n", fill = c(rgb(.059, .412,
.659),rgb(.537, .769, .933)));
abline(v = 0, lwd = 1, col = 1)
dev.off()
