I am new to R and need to create one dataframe from 80 .xlsx files that all share the same columns and are all in the same folder. I want to bind all these files efficiently in a manner that would work if I added or removed files from the folder later. I want to do this without converting the files to .csv, unless someone can show me how to that efficiently for large numbers of files within R itself.
I've previously been reading files individually using the read_excel function from the readxl package. After, I would use rbind to bind them. This was fine for 10 files, but not 80! I've experimented with many solutions offered online however none of these seem to work, largely because they are using functions other than read_excel or formats other than .xlsx. I haven't kept track of many of my failed attempts, so cannot offer code other than one alternate method I tried to adapt to read_excel from the read_csv function.
#Method 1
library(readxl)
library(purr)
library(dplyr)
library(tidyverse)
file.list <- list.files(pattern='*.xlsx')
alldata <- file.list %>%
map(read_excel) %>%
reduce(rbind)
#Output
New names:
* `` -> ...2
Error in rbind(deparse.level, ...) :
numbers of columns of arguments do not match
Any code on how to do this would be greatly appreciated. Sorry if anything is wrong about this post, it is my first one.
