replace a specific strings from multiple columns in a dataframe

Question

I want to replace the strings \"aa\" and \"aaa\" in the dataframe below with\"\"

data = data.frame(attr = c(1:4), type1=c(         


        

Answer 1

library(dplyr)
data2 = data %>%
  mutate(type1 = recode(type1, "aa" = "", "aaa" = ""),
         type2 = recode(type2, "aa" = "", "aaa" = ""))

attr type1 type2
1    1            
2    2     b      
3    3            
4    4     b      

if you wanna generalize, taking from @denis answer:

data2 = data %>%
  mutate_all(function(x) gsub("aa|aaa","",x))
