?barplot
The argument "... space may be specified by two numbers, where the first
is the space between bars in the same group, and the second the space
between the groups. If not given explicitly, it defaults to c(0,1) if
height is a matrix and beside is TRUE ..."
So, try
barplot(t(data), beside=T, ylim=c(0,200), space=c(0.2, 1),
col=c("red","yellow"), main="Species rank curve",
ylab="Number of individuals")
or something like that.
It's helpful to post a small subset of example data along with your code,
so that folks can actually take it for a test drive. It's also helpful to
post example code along with errors/warnings/output from attempts to solve
the problem. You refer to an attempt to try using space, and said "it is
not working" but didn't provide enough information for a reader to know
what you tried and how it didn't work.
