Lately I have felt the need to batch process few of the R scripts I have
been working with and strangely enough I am not able to find a good resource

Operating on each row of data frame
Hi All
I have a data frame in which there are 4 columns .
Column 1 : name
Column 2-4 : values
I would like to calculate mean/Standard error of values in column 2-4 and
store them in column 5,6 respectively.
I have done the following but doesn't seem to work
mean_N_SE <-function(x)
{
name <- x[1]
vals <- c(x[2:4])
temp_mean <- mean(vals)
SE <- sqrt(var(x)/length(x))

dividing values of each column in a dataframe
Hey Guys
I want to divide(numerically) all the columns of a data frame by
different numbers. Here is what I am doing but getting a weird error.
The values in each column are not getting divided by the corresponding
value in the denominator vector instead by the alternative values. I
am sure I am messing up something.
Appreciate your help

Comparing two gff/gtf files : de novo transcripts v/s reference
Hi All
I am wondering if people based on their experience could share what methods
one could use to compare two gff/gtf files. The reason why I want to do so
is that we have constructed a RNA-Seq based transcriptome and would like to
compare it with reference transcriptome we had from in-silico approaches.
Ideally we are looking to find out
1. new genes we see
2. transcripts where the

[LLVMdev] DFG of machine functions
Hi,
I am trying to generate the DFG of machine functions.

was based on the mail thread -
http://lists.cs.uiuc.edu/pipermail/llvmdev/2009-September/025582.html. This
pass worked fine and I was able to generate DFG of LLVM IR functions.
Later, I ported the DFG pass code for machine functions. I ported the
