shell command
Using R (version 0.63.3) for MS windows, I try the following command
> shell(paste("cd ",getenv("RHOME"),sep=""))
which replies with an error message
Too many parameters - FILES\RW0633
which appears to suggest that the space if the path name is causing
difficulties to the cd command. getenv returns
> getenv("RHOME")

R INSTALL -l
The FAQ says in
[5.2 How can add-on packages be installed?]
to install a package to a private tree, use
[$ R INSTALL -l lib pkgdir_1 ... pkgdir_n]
where lib gives the path to the library tree to install to.
which, for me, returns
Package '-l' does not exist. Has there been a change?
Thank you
Ross

adj parameter in mtext
I am trying to adjust the sigma symbol down in the y direction with
the following command but R recycles the sigma and puts another at
-0.1 in the x axis.
Any suggestions would be appreciated.
mtext(expression(sigma),1,outer=TRUE,adj=c(0.5,-0.1))

image legend
I am trying to place a legend onto an image but the legend to
clipped/nonexitent outside the boundary of the image. I am wanting to
place the legend where the main title normally would appear.
I would appreciate someone telling me why I cannot do this. (Which
part of the help file I haven't read most likely)

Need help with function that includes 2 summation
I am relatively new to R, so this may be a much simpler question than it
seems to me. I am trying to create a function that includes two
summations, and can't figure out how. I am attaching the equation as a
pdf file. This function will then be optimized over a chosen range of
values, but right now I just need help with the function. Thank you.

Problems with segments and multiple graphs
I would like to create a page of two graphs (2 rows by 1 col) and then
draw vertical lines (segments?) on both graphs from the minimum
values to the corresponding maximum value.
So I have tried

> par(mfrow=c(2,1))
> plot(y,type="l")
> plot(cumsum(y),type="l")
> segments(1000,min(cumsum(y)),1000,max(cumsum(y)))

Reordering factor levels
I would like to define the order of the levels of a factor.
The relevel function would work but since I have 20 levels I would prefer
to declare the order explicitly. Using a smaller example
levels(oldfactor)
"b1" "b2" "r1" "r2"
nufactor <- order(oldfactor,order=c("b1","r1","b2","r2")) # my fabricated function

A suggestion for predict function(s)
Maybe a useful addition to the predict functions would be to return the
values of the predictor variables. It just (unless there are problems)
requires an extra line. I have inserted an example below.
"predict.glm" <-
function (object, newdata = NULL, type = c("link", "response",
"terms"), se.fit = FALSE,

Nodes & edges with similarity matrix
Hello,
I apologise if someone has already answered this but I searched and
googled but didn't find anything.
I have a matrix which gives me the similarity of each item to each
other. I would like to turn this matrix into something like what they
have in the graph package with the nodes and edges.

Level(3) SIP termination services
John,
I spoke with Level(3) last week regarding SIP termination. They
quoted $0.01/minute, with an 11 Million Minute / Month minimum.
Ugh!

Histogram without common borders
Is it possible to produce a histogram directly using the hist()
function with the common borders removed?
It can be done by plotting the histogram object using type 's'teps.
my.hist <- hist(x,plot=FALSE)
plot(my.hist$breaks,c(0,my.hist$counts),type='s')
I would appreciate help
