Thank you for your quick answer.
I have this error message :
"Warning: Error in : '"TOA5","Meteo_GreEnER_CR6","CR6","8957","CR6.Std.10.01","CPU:METEO_GREEN-ER_v2.4.CR6","5234","_01_Min"' does not exist in current working directory"
I read the file like this :
chemin_min_rea <- reactiveFileReader(1000, NULL,chemin_min, readLines)
and then, I try to make a dataframe to be able to draw a graph :
read_csv(chemin_min_rea, col_types = cols(.default = "c"), skip = 1 )
That was working with the version 1.4.0 of the readr package
"TOA5","Meteo_GreEnER_CR6","CR6","8957","CR6.Std.10.01","CPU:METEO_GREEN-ER_v2.4.CR6","5234","_01_Min" is the first line of the file that is seems to be read as a file by read_csv.
