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

This should do the trick if you are looking for a new variable

library(tidyverse)

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

df <- data.frame(round, experiment, results)
df

df <- df %>% mutate(
  name = paste(round, experiment, sep = "_")
)
