How to convert the name of a dataframe to a string in R?

Question

I am looping over a list of dataframes in R and want to use their names as part of the filename I save my plots under.

The code below is my attempt at iterating thro

Answer 1

Slightly different solution:

dataframe1 = data.frame(iv = rnorm(50), dv = rnorm(50))
dataframe2 = data.frame(iv = rnorm(50), dv = rnorm(50))
dataframe3 = data.frame(iv = rnorm(50), dv = rnorm(50))

LIST = list(dataframe1 = dataframe1,
            dataframe2 = dataframe2,
            dataframe3 = dataframe3)


for(i in 1:length(LIST)){
  pdf(file=paste(names(LIST)[i], paste(colnames(LIST[[i]]), collapse="."), 
                 "pdf", sep="."))
  plot(LIST[[i]][,1],LIST[[i]][,2], 
       xlab = colnames(LIST[[i]])[1], 
       ylab = colnames(LIST[[i]])[2],
       main = paste("Plot based on data in", names(LIST)[i]))
  dev.off()
  }
