I have 12 dataframes (df1:df12). All of them have a column named "gene". I would like to search for a specific character string, say "GeneX", in the "gene" column in all the dataframes and print the line with the string.
Right now I'm using 12 lines of code to do this.
df1[grep("GeneX", df1$gene), ]
df2[grep("GeneX", df2$gene), ]
We can keep the datasets in a
list and check for 'GeneX' with
grep on 'Gene' column, subset the rows.
lst <- lapply(mget(paste0("df", 1:12)), function(x) x[grep("GeneX", x$Gene),])
