Concatenating two text columns in dplyr

Question

My data look like this:

round <- c(rep(\"A\", 3), rep(\"B\", 3))
experiment <- rep(c(\"V1\", \"V2\", \"V3\"), 2)
results <- rnorm(mean = 10, n = 6)
         


        

Answer 1

You can use the unite function from tidyr

require(tidyverse)

df %>% 
  unite(round_experiment, c("round", "experiment"))

  round_experiment   results
1             A_V1  8.797624
2             A_V2  9.721078
3             A_V3 10.519000
4             B_V1  9.714066
5             B_V2  9.952211
6             B_V3  9.642900
