ROWNAMES error message
I am getting an error message, which I do not know the source to.
I have a matrix SAMPLES that has preexisting rownames that I would like to
change.
GENE_NAMES contains these rownames.

a newbie seeking for a simple problem
Dear Experienced R users,
I have a looks-like simple but complicated problem urgently needed to be solved. Below is the detail:
I have two dataframes, df1, df2. df1 contains two column and many thousands rows: column 1 is a "gene_name", column 2 is "value". df2 contains only one column which is "gene_name" with couple hundred rows. I want to change "value" of df2 for those "gene_name" also appear in df2 "gene_name". How to do that? Millions thanks.

help with rowsum/aggregate type functions
Hi--
This is a question with a trivial and obvious answer, I'm sure, but I can't seem to find it in the help files and books that I have handy. I have a dataframe consisting of two columns, "Gene_Name," a list of gene symbols, and "Number," a numeric measure of how frequently a tag representing that gene showed up in a SAGE library. Several of the genes are represented by multiple tags, and therefore are present more than once in the list, e.g.:
1167 Zcchc8 6
1168 Z...

Plotting Character Variable
Any ideas about the following problem:
I have a matrix (A) that looks like this:
gene_names values

hsa-mir-333 0.7

(This is a 2 by 22283 matrix: quite large)
I would like to plot the values, but output the gene_names as the plotting
symbol. I ha...

R eat my data
HI, Dear R community,
My original file has 1932 lines, but when I read into R, it changed to 1068
lines, how comes?

Two questions about metacharacter in regexprs and function return
for the script, please kindly see the script below. At line 10 and line 13,
my problems occurs.
The first one is I try to retrieve the gene official name from a column of a
table. The pattern of official name is something starting with gene_name.
For detail problems, please see the according lines.
Any suggestions are appreciated
example of matching source (extract the Nnat, sometime it would be the
character "N/A"):

Correlation analysis
...I would like to perform a correlation analysis between a hiv data and gene
expression.
Basically, i have a file that contains: hiv_name, start_position,
end_position, chromosome. I would like to see if these data has anything to
do with the location of our genes (I also have another file contains
gene_name, start_position, end_position, chromosome).
What functions that allow me to do this?
I am very new to R and hopefully someone can guide me to the right
direction.
Thank you very much,

Is that an efficient way to find the overlapped , upstream and downstream rangess for a bunch of rangess
...ne4 chr1 20 25 6 +
gene5 chr1 30 40 11 +
I just wondering is there an efficient way to find *overlapped, upstream
and downstream genes for each gene in the granges*
For example, assuming all_genes_gr is a ~50000 genes genomic range, the
result I want like belows:
gene_name upstream_gene downstream_gene overlapped_gene
gene1 NA gene2 NA
gene2 gene1 gene4 gene3
gene3 gene1 gene4 gene2
gene4 gene3 gene5 NA
Currently , the strategy I use is like that,
library(GenomicRanges)
find_overlapped_gene <- function(idx, all_genes_gr) {
#cat(idx, "\n")

Creating a Hash from Data.Frame
Hi,
I have the following data frame:
> print(mydatframe)
__DATAFRAME__
V1 V2 V3
1 1007_s_at DDR1 discoidin domain receptor tyrosine kinase 1
2 1053_at RFC2 replication factor C (activator 1) 2, 40kDa
3 117_at HSPA6 heat shock 70kDa protein 6 (HSP70B')
__END__
Is there a way to create a hash with
V2 as Key and V3 as its value?
