Replicate more than one column [duplicate]

Question

I am trying to sample 2 columns of a dataframe but the sample function is allowing me only one column to sample not both columns(Campaignid,CampaignName) at once.

Is there a way to sample like I wanted!

camp.d <- data.frame(Campaignid=c(121,132,133,143,153),
                     CampaignName=c('a','b','c','d','e'))

#allows only one column
a <- sample(camp.d$Campaignid, 100, replace = TRUE)

Expected:

Campaignid CampaignName
  121             a
  121             a
  133             c
  132             b
  132             b
...

Answer 1

I think you need this -

sampled_data <- camp.d[sample(nrow(camp.d), 100, replace = T), ]

head(sampled_data)

    Campaignid CampaignName
2          132            b
5          153            e
3          133            c
3.1        133            c
2.1        132            b
4          143            d
