[R] capturing warnings within loops, so I know the iterations where warnings occurred?

I am running a loop. Warnings sometimes occur, and the lop continues until the end. For each iteration of the loop, I wish to capture and "save" any warnings issued, so that I can tell on which iteration the warnings were issued. I tried this, but it does not work. mylist <- list(NULL) mylist_war

[R] when to use & pros/cons of dataframe vs. matrix?

When "should" I use a dataframe vs. a matrix? What are the pros and cons? If I have data of all the same type, am I usually better off using a matrix and not a dataframe? What are the advantages if any of using a dataframe vs. a matrix? (rownames and column names perhaps?) ___

[R] pasting columns of a dataframe together

I want to "paste" the contents of the first column of a dataframe with all the columns of the same dataframe. What is a "good" way to do this, perhaps something more elegant than what I have below. (My actual dataframe has ~400 columns and ~35000 rows.) example1: mydf <- data.frame( matrix

I am a relatively new user to R, and I am trying to learn more about converting data in an XML document into "2-dimensional format" such as a table or array. I might eventually wish to export this data into a relational database such as SQL, and/or to work with this data within the R package. My
