Hello!
I keep having this error when I run my program and I have seen many people struggling with the same problem, but since I am a beginner with RStudio and I struggle a lot with computers, I don't know how to solve it by myself 
The program that I use is from this tutorial (sorry it's in French). It is supposed to provide a way to properly format a corpus of news papers publications (in HTML format), to be able to perform a lexicometric analysis with Iramuteq .
Here is the whole part that I'm struggling with (I'm sorry if it's long, I have no idea what I'm supposed to add or not ).
setwd(dir = "D:/testrstudio")
load.lib <- c("xml2", "XML", "stringr", "stringdist", "stringi","lubridate", "dplyr", "tidyr", "ggplot2")
install.lib <- load.lib[!load.lib %in% installed.packages()]
for (lib in install.lib) install.packages(lib,dependencies=TRUE)
sapply(load.lib,require,character=TRUE)

The error is in french but it's the same as "arguments imply differing number of rows".
I can't figure out how to join the HTML file that I use with this program, if you need it, let me know and I'll try to find another way to send it to you!
