hi -
sorry for a newbie question, but I've tried to go through the
documentation and couldn't find anything that would address my specific
need.
in a nutshell, I have a txt file containing a data matrix with 10
columns of data. I would like to generate pairwise plots of the data,
i.e. 1
Peter,
Please read the intro to R available on the R web page - you've run
into a subsetting problem. The code you specified doesn't select a
column from your matrix.
plot(test[1], test[2)
Try:
plot(test[,1], test[,2])
since test is a two-dimensional construct.

Hi Rolf,
If your data come from exponential family of distributions, then the
log-likelihood is concave and the observed information must be positive
definite. However, I don't think that this is the case more generally, i.e.
for families such as curved exponential families the log-likelihood
