df <- data.frame(x = 1:12, y = rnorm(12)) If you use sample:
RowIndex <- sample(1:nrow(df), 5) TrainSet <- df[RowIndex, ] TestSet <- df[-RowIndex, ] Or with dplyr: TrainSet <- sample_n(df, 5) TestSet <- anti_join(TestSet, df) HTH Ulrik On Fri, 9 Dec 2016, 06:56 Partha Sinha, <pnsinh...@gmail.com> wrote: > How to get two sets of non overlapping data? > Regards > Parth > > On 8 December 2016 at 23:23, Ulrik Stervbo <ulrik.ster...@gmail.com> > wrote: > > In addition to 'sample', and if you insist on dplyr, you can use > 'sample_n'. > > Best, > Ulrik > > On Thu, 8 Dec 2016 at 18:47 Bert Gunter <bgunter.4...@gmail.com> wrote: > > Usually we expect posters to do their homework by reading necessary R > documentation and relevant subject matter resources (e.g. on > clustering) and making a serious attempt to solve the problem by > offering their code to us along as part of a reproducible example of > how it failed.
