It is sure thing that different person has different expectation of
the help system. Personally, I think Stata's on-line help system is
too brief, though the manual may be a different story. Perhaps, it is
all about the habit and the extent to which you are used to (and how
much you know about it).
Can you just print what you need to know? For example:
> fact <- function(x) {
+ if(x<1) ans <- 1 else ans <- x*fact(x-1)
+ print(sys.call())
+ cat(sprintf("X is %i\n",x))
+ print(ans)
+ }
> fact(4)
fact(x - 1)
X is 0
[1] 1
fact(x - 1)
X is 1
[1] 1
fact(x - 1)
X is 2
[1] 2
fact(x - 1)

Looking at ?contourplot, it would appear it should be ok to set region=TRUE.
So this is a case of "time to explore".
Have you tried levelplot instead of contourplot? The default for
levelplot is region=TRUE, vs region=FALSE for contourplot. If
levelplot also fails, that tells you something dif
I used points graphic (geoR) in this way:
points(zn,pt.divide=c("quintiles"),
main="Location map of Zn",lambda=1,col="gray",yl="coord y",xl="coord x",x.leg=0.
3, y.leg=5.5,dig.leg=2,cex.min=0.5,cex.max=1,)
Can I reduce legend characters

I have csv files imported in r each with 2 columns and many many rows. I have
sorted the data in them but want to extract some values.
The first column is an ID
The second is a p-value ( now sorted in increasing order with NA's last)
I want to extract the rows with a p-value of less than 0.05)

This question is not a stats question per say but a data management and
lattice plotting problem. I apologize now if I'm asking an inappropriate

re-scaling the data. But, if anyone can explain to me why throwing the

Ok, I'll try to explain my issue. I have a monthly series (CPI index) and I

Is there a way to change the default settings for Sweave figure output?
Sweave produces an .eps and a .pdf file as output (7x7 inch). Changing pdf
defaults changes the pdf() function output size but does not affect the pdf
size produced by Sweave.
