Dear Colleagues.
I believe this should be a problem encountered by many:
nls( ) is a very useful and efficient function to use if we are just to
display the estimated value on screen. What if we need R to store the
estimated parameter in a variable?
For example:
x=rnorm(10, mean=1000, sd=10)
Hi,
I have imported a data file to R. Unfortunately R has interpreted some
numeric variables as factors. Therefore I want to reconvert these to numeric
vectors whose values are the factor levels' labels. I tried
as.numeric(factor),
but it returns a vector of factor levels (i.e. 1,2,3,...) instead
See the FAQ Q7.10 (and please study the posting guide)

Hello!
Can anyone help me. I am using the posterior.mode from the result of glmmML.
It apears to be different from the BLUe estimate of the RANDOM statement in
PROC NLMIXED
in SAS. Why is that?
Thank you

For example, if I have the values:

I have a problem when I want to put a legend on the graph.
I do:

Dear R users
Is there a way to include in a figure the 2 sided p value obtained with the crr
function in the package cmprsk
Such as the one for cuminc:
text(3.5,0.05, adj=0, paste(Gray test: p-value = , round(fit1$Tests[1,2],3)))

If you are asking to have the values plotted on top of the legend,
then you can do the following:
plot(x, y, type='n', ...) # create plot, but don't plot
legend('topright', ...)
lines(x,y) # now plot the data
If you want it outside the plot, check the archives for several examples.

Here is a way that you can put the formatting that you want; you were

Every loop of my program will result in a list that is very long, with a

I need to store all such lists in a csv file so that I can easily

Hi Adschai,
R has a class for tree-like structures. See the 'tree' package.
