delete columns

  • 772

I have the following problem in Rstudio. I am using write.tableto save my file in .SIF format, and what happens is that I want to remove 2 columns out of the 5 that I have, I am trying to do it with the following code:

write.table(temp, 
          file = paste("./", nombre.carpeta, "/", gen, ".SIF", sep=""), 
          quote = FALSE, row.names = F) %>% temp %>% 
select(temp, -c(abs.value, signo))

... and it gives me an error, so please help me with this, in this case I want to eliminate the columns abs.value and sign

    You have some misconceptions:

    1. When you use the "pipe", you precisely avoid having to pass the result of each "verb" to the next, in your case tempyou are copying it in each function.
    2. The order is not correct: first we start from tempthen we eliminate columns and finally we save the file

    Your command batch should look something like this:

    temp %>% 
  select(-c(abs.value, signo)) %>% 
  write.table(file = paste("./", nombre.carpeta, "/", gen, ".SIF", sep=""), 
              quote = FALSE, row.names = F)
