Counts the number of observations within each group for each peptide and divides by the number of replicates – defaults to one replicate per sample.

1	count_df(dat, col, rep = 1)

`dat`	a data frame containing samples and observations to be counted
`col`	a numeric vector containing the column numbers of the group to be counted
`rep`	number of replicates for each sample defaults to one.

# selects the columns containing a string that identifies the group
group1 <- grep("Sample_norm", colnames(data))
# three analytical replicates were run for each
data$group1_df <- count_df(data, group1, rep = 3)
