Hello,
I have stumbled across a peculiar problem. I am writing code for a
simulation, and would like to package it into a function that completes one
iteration. I'm using covTest sig. tests for LASSO (link is below to info
and the source code). When this function is used within a function (F.1

First, thank you. It's amazing how many things R has built in... such

I'm still pretty new to R, and often am unsure of what I am doing. In this

I decided to use JAGS instead. The unmodified JAGS code runs fi

Hi Marta,
It's not clear whether you wanted to select the first "n" rows specified by
field2 in the first dataset or just random rows.

c("field1",
"field2"), class = "data.
Hello,
I've just noticed that na.strings is not needed and will not be used by
readHTMLTable. I was with the false impression that the dots argument
was to pass other arguments to read.table, but it's not, they're passed
to as.data.frame, that doesn't use na.strings.

If my arithmetic and understanding is correct, that's 32 billion

That is what I was trying to achieve; i.e. plot all my graphs using a loop
function. But somewhere in the loop it converts each graph into png or
bitmap image and then compiles all these png or bitmap images in a pdf file.
So each page in a pdf file is a bitmap or png picture of my graph.
