Hi thank you in advance for your assistance. I am using the following section of script:
DirPath_folder <-Sys.glob(file.path("/Users/catpeters/Documents/R_working_directory/1_Data_MC_Sorted")) for (folder in 1: length(DirPath_folder)) { # ## EVERY Control and Impact # DirPath_Matrix <-Sys.glob(file.path(DirPath_folder[folder], "*Markov_Matrix_Month.txt")) data <- read.table(DirPath_Matrix, header = TRUE, sep = ";") if (folder ==1) { DATA_ALL1 <- data } else { DATA_ALL1 <- rbind(DATA_ALL1, data) } if (folder == length(DirPath_folder)) { setwd("/Users/catpeters/Documents/R_working_directory/1_Data_MC_Sorted") write.table(DATA_ALL1 ,"Matrix_Markov_ALL_MONTH_RB.txt" , col.names=TRUE, row.names=FALSE, sep=";") write.table(DATA_ALL1 ,"Matrix_Markov_ALL_MONTH_RB.csv" , col.names=TRUE, row.names=FALSE, sep=";") } } There seems to be a problem with: data <- read.table(DirPath_Matrix, header = TRUE, sep = ";"). When run it returns the Error in file(file, "rt") : invalid 'description' argument. This has worked previously and I'm not sure where the error is.
