The on-line documentation for par() refers to a 'gamma'
argument.

Documentation of par(ann) (PR#539)
The on-line documentation for the 'ann' argument under
par(), states "If set to 'FALSE'...". However, this
parameter shows up as a numeric on my machine, not as a
logical.

Typo in documentation for order() (PR#541)
The documentation for 'order()' has the following sentence:
`sort.list' is the same, using only one argument put
allowing
partial sorting.
Should "put" be "but" or possibly "'partial'"?

Non linear regression using Levenberg-Marquardt method
Hello,
I want to fit some non linear models with the Levenberg-Marquardt
algorithm. It doesn''t seem to exist any function to do this in R ( well,
maybe one does, but I''m a new user, and the only documentation I have is
"An introduction to R").
I''d like to know if this function exists, maybe throught an additionnal
package.
I''d also like to know if if

How do you go beyond tapply()?
...ants
are indexed by both state and sex?
Is there a way to use tapply() to put the vector into bins
defined by the levels instead of having to exactly match the
levels? It seems some sort of historgramming is what's
needed, but hist() does plots, not just the categorization
into bins.

Percentile function
...ponding to the value?
Something like
pvalue<-function(x,vector){mean(x>=vector)}
but with interpolation.
Given the above function, is there a way to do the following
without the loop:
for(i in 1:10) y[i] <- pvalue(x[i],vector)
where x and y are numeric vectors of length 10?

Comments on Win95 R Distribution (PR#527)
...for doing the examples in the Intro.
The rwinst.exe did not work at all on Win95. It could find
no files. Wasn't clear from the instructions which
directory I should be in while running rwinst. I tried
several; none worked. So I manually unzipped the files and
they worked fine.

Cutting vectors
I have one factor with say five levels (fact) of different size and a corresponding variable (var). I randomly generate five new levels (nfact ex. 2,2,1,5,4). What I would like to do is to extract the corresponding variable values into a new variable (nvar). I did try the following, why doesn't it work? nvar<-var[fact==nfact[ ]]
