Hi All,

I have a table with six columns (in the following).

So, I want to delete SNPs that are less than number 10 in the SNP column.

What is the best idea?

Read the file, and filter out any row where SNP column is more than or equal to 10:

    data <- read.table("SNP.txt", header = TRUE)
    data <- data[ data$SNP >= 10, ])


To exclude 1st BP column, and to add 20KB to BP column:

    data <- data[ , -3 ]
    data$BP <- data$BP + 20000
