How to get passed the following error "Error in readLines(filestocopy) : 'con' is not a connection"?

I am new to coding and very new to this forum, so I hope my request makes sense.
I am trying to select images listed in a .csv file and to copy them to a new folder. The pictures and the .csv file are both in the folder GRA04. The .csv file contain only one column with the picture names.
I used the following code:

#set working directory
setwd("E:/2019/GRA04")
 
#create and identify a new folder in R
targetdir <- dir.create("GRA04_age")<br/>
 
#find the files you want to copy
filestocopy <- read.csv("age.csv", header=FALSE) #read csv as data table (only one column, each raw being a file name)
filestocopy_v <- readLines(filestocopy)#convert data table in character vector
filestocopy_v #shows the character vector

#copy the files to the new folder
file.copy(filestocopy_v, targetdir, recursive = TRUE)

When reaching the line

filestocopy_v <- readLines(filestocopy)

I get this error message:

Error in readLines(filestocopy) : 'con' is not a connection

I looked online for solutions with no luck. I ran this code before (or else something similar... didn't back it up...) and it worked fine, so I am not sure what is happening...
Thanks!

Out of interest, would the following now do what you're trying to achieve?

filestocopy_v <- filestocopy[[1]]
