The on-line documentation for par() refers to a 'gamma'
argument.
However, if 'par()' is invoked, there is no 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

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'"?

Percentile function
Is there an R function that inputs a value and a vector, and
returns the percentile corresponding 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)
Here are some comments generated by a new R user based on
initial experiences with the tool.
On-line help for tapply:
The following appears "for to each (non-empty) group of
values" It seems there's an extra preposition in this
sentence.
On-line help for cut:
"break" should be "breaks"

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

Dear r user,
please find my attached sample of the dataset i? am using to create a crosstable and eventually plot a histogram from the output.

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[ ]]

If the server decision makers had not gone for a server designed by
accountants but a server designed by engineers then you would not have this

Determining model parameters
This may be a begining question. If so, please bear with me.
If I have some data that based on the historgram and other plots it "looks" like a beta distribution. Is there a function or functions within R to help me determine the model parameters for such a distirbution? Similarily for other "common" distirbutions, Poisson(lambda), Chi-Square(degrees of freedom, chi-square

samba & unix group permissions problems
Hi,
I'm having permissions problems connecting to a share when the gid of
the directory shared is not the primary group of the user connecting to it.
Maybe I faced it the wrong way, but I did read (and at least thought I
understood) the 'File, directory and share access controls' section of
the howto [0].
My users have either one or another 'primary group' (the one set in

hist, lines, rug
Hello,
I'm trying to plot a historgram with a density plot superimposed:
hist(x, seq(-1, 1, by = 0.1), prob = T, col = "blue")
lines(density(x, bw = 0.1))
rug(x)
I don't want to add rug(x) but the histogram will not be plotted unless
rug(x) is there. It does not work if the "hist" line alone is present.
Can you help?
Thanks,

standard errors in johansen test

I have a question. How to get the standard errors of alpha and beta

Models: Implementation Within R Package” pp.24-25. The standard errors are
listed on the table 5 following the code:

Samba and unix permissions mismatch
I have just managed to get my first Samba/LDAP PDC up and running. But
I have one big security problem -- users logging in to the PDC using
ssh can access all shares.
User credentials, both for ssh login and for Samba access, are retrieved
from the LDAP directory. All shares are stored in the /var/lib/samba
directory. The directories permissions look like this:
drwxrwx--- 2 root Domain
