Do not want scientific notation on plot axis

Use options(scipen=5) or some other high enough number. The scipen option determines how likely R is to switch to scientific notation, the higher the value the less likely it is to switch. Set the option before making your plot, if it still has scientific notation, set it to a higher number.

You can use format or formatC to, ahem, format your axis labels.

For whole numbers, try

x <- 10 ^ (1:10)format(x, scientific = FALSE)formatC(x, digits = 0, format = "f")

If the numbers are convertable to actual integers (i.e., not too big), you can also use

formatC(x, format = "d")

How you get the labels onto your axis depends upon the plotting system that you are using.

Try this. I purposely broke out various parts so you can move things around.
