Hello I have 2 data frames df1 and df2. I would like to create a new data frame new_df which will contain only the common rows based on the first 2 columns (chrN and start). The column score in the new data frame should be replaced with a column containing the average score (average_score) from df1 and df2. df1= data.frame(chrN= c(“chr1”, “chr1”, “chr1”, “chr1”, “chr2”, “chr2”, “chr2”),

I want to remove the column names from a data frame.

Good Night. I'm implementing a Interference Graph in the Register Allocation pass. I'm building this graph BEFORE any assignment of a virtual register to physical register. But I have a doubt about how to check the interference between two Live Intervals (i.e. They live at same point), should I use: L1->overlaps(L2) Where L1 and L2 are two different Live Intervals. Or should I use:

Dear all, I have the following data frame: V1 V2 aaa chr1 aaa chr2 aaa NM aaa QC aaa chr10 att NM att chr7 What I want to do is to count the string (V1). But the condition of counting is: if the V2 of the string is "NM" or "QC" then the count is not increased. Hence the contigency table will look like this: #tag count aaa 3 att 1 Is

Hi I am really sorry for this probably quite simple question. I am new to R, and I am running a pipeline that has already been made. All I have to do is give the paths for different folders, where the pipeline can find the files with my data. But every time I try to run the pipeline it returns with the message, that it cannot find the file. And I really don't know why. I have found the path
