error no applicable method for 'select_' applied to an object of class "character"

Question

Here is my script (I try to: read csv -- rename all columns name -- select some of the columns and write the output as another csv)

but I get error for select function:

Error in UseMethod("select_") : no applicable method for 'select_' applied to an object of class "character"

Here is my code:

 Old_Data <-
 read.csv("K:/International/New Miestone.csv", stringsAsFactors = FALSE)
names(Old_Data) <-
    c("Enrol.Year",
    "VTAC.Course.Code",and so on)%>%

select(
"Enrol.Year", and so on)

write.csv(Old_data,path,.....)

Strangely, I used to import data from txt file and set names for headers, then select, then write csv, never has such problem

Answer 1

library(dplyr)

#Read the csv
Old_Data <- read.csv("K:/International/New Miestone.csv", stringsAsFactors = FALSE)

#Rename all the columns and select required columns
New_Data <- Old_Data %>%
             rename_all(funs(c("Enrol.Year", "VTAC.Course.Code",...))) %>%
             select(Enrol.Year,  VTAC.Course.Code, ...)

#Write the csv
write.csv(New_Data,path)
