Hi all,
Julian just reminded me I need to include the lines of code so here it is
below.
I am trying to run some plots on data, but when loading the CSV data file it
doss that but in ggplot R is stopping and I am getting an out of memory
error.

Anyway to tweak this somehow to get it to run?

If you really do have a data file called batcalls.rda, then the proper
way to get it into memory is with:
load("C:/Rainey//batcalls.rda") # replace path with the actual path
on your system and remember not to use "\"'s
attach(d)
Error in attach(d) : object "d" not found
Because of the error ... nothing got done.

You cannot do anything on something that isn't there

attach(batcalls)
print(qplot(Fc,geom="density"))
b<-kmeans(Fc,c(10,15,18,30))
print(qplot(Sc,Fc,colour=as.factor(b$cluster)))

print(qplot(Dur,Fc,colour=as.factor(b$cluster)))
d <- read.csv ("C:/Rainey/RainyAllbats.csv")
OK, that appears to have run without error, so it fits into memory. Now you should run: str(d) # and report the results
attach(d)

You seem to be ignoring all the informative error message.

WinXP in its default state can only use around 2.5GB and that may require upping the memory limits: <http://cran.r-project.org/bin/windows/base/rw-FAQ.html#There-seems-to-be-a-limit-on-the-memory-it-uses_0021 > And read the material in the links from that page as well.
