vector for file names
files<- list.files(path = "C:/Users/91932/Downloads/archive (2)/Fitabase Data 4.12.16-5.12.16",pattern =".csv")
concat directory to file names
files<-str_c("C:/Users/91932/Downloads/archive (2)/Fitabase Data 4.12.16-5.12.16",files)
applying function to each element of vector
> map_df(.x = files, .f = read.csv,)
in above function map_df() i am getting an error in file (file,"rt"), even after using setwd() to set path and checking using getwd() paths seems to be correct for .csv file .
why this error occurred? how to avoid such errors?
>Solution :
The error is because the path is wrong: you forgot the trailing slash in the path prefix in str_c. However, rather than using str_c, you can instruct list.files to give you full paths from the get-go:
files <- list.files(
path = "C:/Users/91932/Downloads/archive (2)/Fitabase Data 4.12.16-5.12.16",
pattern = ".csv",
full.names = TRUE
)
