Hi to everyone
To simulate data I only know this command:
rnorm(n , mean, sd)
It exists another way to specify Median and range as well?
The point is that I have this information about the variable:
Median: 4.3
Mean: 4.2
SD: 1.8
Range: 0-8
and I need a boxplot, but I don't have the origin

Any idea is welcome.
Hi Teresa,
You can get the return value from the boxplot

Thanks everyone for al your help, I don't think it's necessarily as easy as

I'm going to have a think about it and try some things out. And I'll be

Hi Teresa
Try this:
Median <- 4.3
Mean <- 4.2
SD <- 1.8
RangeLower <- 0
RangeUpper <- 8
par(mfcol = c(1,2))
(bpstats <- boxplot(rnorm(100, mean = Mean, sd = SD), outl = FALSE))

I have a list of cities and their coordinates, and also for each city I have

#or
dat2$Col1[dat2$Col1==''] <- NA
