Correlation analysis
Hi everyone,
I am new to R-project. I did search through the list for my problem but i
can't find it. I am sorry if this question has been asked.
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...
