Question

i have a very big data frame((35000 line) but i want to get specific rows by skipping for example 100 row.

so in this case each 100 row I’ll just get one row.

i know that it can be done using:

N = nrow(dataframe)
   for( i in seq(1:N,by=100))
   { 
   out <- rbind(out, data.frame(...)

    }

is this can be done more easily than a for loop?? using subset or something like this

regards

Answer 1

Use something like this:

dataframe[seq(1, nrow(dataframe), 100), ]
