如何读取.csv 列作为逻辑而不是字符？

Question

Into a csv file I have a column which contains logical operator values TRUE, FALSE.

When I use read.csv as following

it reads the column as character. How can I modify read.csv() to read it as logi?

I use this option of read as I have multiple csv files

files <- list.files(path = "C/path/files",pattern = ".csv")
temp <- lapply(files, fread, sep=",")
dframe <- rbindlist( temp )

Use the colClasses argument of the read.csv function. Provide a character vector of classes for the columns in your data set.

From the help page of read.csv :

colClasses character. A vector of classes to be assumed for the columns...
