hello, I am trying to extract the fold change of several genes from a list resFilt and I tried the use the code below, but I got an error. is the code for extracting the genes is wrong?

myterms <-read.table("GO-0004553.txt", header= FALSE)
head(myterms)
typeof(resFilt)
head(resFilt[[1]])
de<- resFilt[resFilt$table %in% myterms$V1]

# 
>myterms <-read.table("GO-0004553.txt", header= FALSE)
> head(myterms)

Probably:

resFilt[rownames(resFilt$table) %in% myterms$V1,]

You have to tell the function what it should compare with myterms. In your case that is the rownames, not the entire table itself, that makes no sense.

Alternatively:

resFilt$table[myterms$V1,] 

should work as well. Please be sure to read about basic filtering/data manipulation in R.
