How to write the dataframes in a list to a single csv file

Question

I have a list with 15 data frames and they look like this

> head(final_data[[1]])
      DateTime # Unemployed Persons.csv
147 2013-03-01                          


        

Answer 1

you can use the join-functions from the dplyr-package an put them in a loop like this:

library(dplyr)
#example list
list <- list(
  data.frame("Date" = seq(as.Date("2016-01-01"), as.Date("2016-02-01"), "days"), 
             "a" = 1:32), 
  data.frame("Date" = seq(as.Date("2016-01-01"), as.Date("2016-02-01"), "days"), 
             "b" = 33:64), 
  data.frame("Date" = seq(as.Date("2016-01-01"), as.Date("2016-02-01"), "days"), 
             "c" = 65:96))

for (i in 1:length(list))
  if(i == 1) df <- list[[1]] else
    df <- left_join(df, list[[i]])
