Dear R community,

Please help.  I am new(ish) to R and have spent too many hours trying to
achieve what I believe should be a relatively simple task.  I have searched
help forums, but have not been able to successfully apply responses to
loosely related questions to my own.

I am running some preliminary summary statistics.  I wish to create a
boxplot graph that represents summaries of samples collected over a series
of time points (0-18).  My sample collection intensity was highest early
on, with samples collection decreasing in frequency over time.  I am trying
to scale the the x-axis to unequal intervals.

The code I used for a graph representing a subset of my sample (re-named)
is below:

Boxplot(ALL~sample, data=rich.small, id.method="n", las = 2, names =
c("0","2","4","7","10","18"))

There were 10days between samples 0&2 and 3 days between 2&4, 4&7, 7&10,
and then 75days between 10 &18

Thanks
