Hello all!

I have the following problem with the %in% command:
 
1) I have a data frame that consists of functions (rows) and genes 
(columns). The whole has been loaded with the "read.delim" command 
because of gene-duplications between the different rows.
2) Now, there is another data frame that contains all the genes (only 
the genes and without duplicates) from all the functions of the above 
data frame.

What I want to do now is to use the "% in %" command to obtain a 
TRUE-FALSE data frame. This should be a data frame, where for every 
function some genes are TRUE and some are FALSE depending if they were 
or not in the specific function when matched against the "all genes" 
data frame.

The main problem I have is the way how the genes are in the first data 
frame. I used the "unlist" command to separate them through commas ",". 
But every time I do the match between the first and second data frame it 
returns out FALSE for every gene in every function.

Can anyone please give me a hind how to handle the problem?
Thank you very much in advance!

Paul
