read a csv file in a zipped folder with R without unzipping

Question

I have a zipped file named master.zip which contains 2 CSV files inside it: file1.csv and file2.csv

I want to read file1.csv only, something like: read_csv('master/file1.csv') , but without having to unzip master.zip . How can I achieve this with R?

Answer 1

You just need to use the native function unz() . Let's assume that master.zip is in your working directory,

# just a list of files inside master.zip
master <- as.character(unzip("master.zip", list = TRUE)$Name)
# load the first file "file1.csv"
data <- read.csv(unz("master.zip", "file1.csv"), header = TRUE,
                 sep = ",")
