Exponential regression
...an intercept term --
y = a + c*exp(b*x)
You need nonlinear least-squares or maximum likelihood to fit it.

Burt table from word frequency list
Dear all,
I have a word frequency list from a corpus (say, in .csv), where the
first column is a word and the second is the occurrence frequency of
that word in the corpus. Is it possible to obtain a Burt table (a
table crossing all words with each other, i.e., where rows and columns
are the words) from that frequency list with R? I'm exploring the "ca"
package but I'm

Using sapply to build a count matrix
Dear All,
I am new to R and slowly learning how to use the system.
The following code is an exercise I was trying.
The intent is to generate 10 random samples of size 5 from
a vector with integers 1:10 and 2 missing values. I then want
to generate a matrix, for each sample which shows the frequency
of missing values (NA) in each sample. My solution, using sapply
is at the end.
If anyone has the

I want to see the source codes for "dchisq(x, df, ncp=0, log = FALSE)",

I input "dchisq" in the R interface, and then enter, the following message
return:

...as the NEAREST co-occurence (so
the cat and the rate chased the dog
would count as two at delta=3 but not one at delta=6) it will be trickier
and I'm not sure this approach can be modified to handle it.

Question about contributed packages
I am working on a methodology for qualifying R, for GLP and GCP.
If I quailfy only the base R install, with no contributed packages, it
seems relatively simple to qualify R. However, from time to time I
will want to use a contributed package. If I use a contributed package,
does it leave anything behind that will be loaded with the next invocation
of R?
Suppose I run R and use a contributed
