Hi,
I am new to glmnet, so I do not yet understand fully what the various
parameters do. I am trying to build a multinomial classifier which restricts
the number of features used in the model. From reading the docs and some
answers on this forum, I understand dfmax is the way to do it. I
Is there any package available for estimating Panel VAR. Can the packages
vars and palm be combined in some way to do that?

Hi Guys
I am back with another thing that's puzzling me.
I am creating contingency tables but then I want to filter out certain
columns and also find if any entry in the table is 0.
Example:

121 127 120
223 112 0
Here I want to remove B2 column
Hey Guys
Getting spinned about a slick way to join every 2 entry in a list / vector
in R
x=(rep(c('A','G','C','T'),1000))
A G C T A G C T etc
form another list with entries as
AG CT AG etc
so join the first 2 and so on.
Thanks!'

Hi Alex
merge wont write a file automatically. You need to use something which
can direct the output to a file.
write.table(merge12, file = output.data ) should do the trick.

correct results
since it is possible for two chromosomes to have a SNP at the same bp
