I need to read several csv files from a directory and save each data in separate dataframe.
The filenames are in a character vector:
lcl_forecast_data_files <- dir(lcl_forecast_data_path, pattern=glob2rx("*.csv"), full.names=TRUE)
For example: "fruc2021.csv", "gem2020.csv", "strb2021.csv".
So far I am reading the files step by step:
fruc2021 <- read_csv2("fruc2021.csv")
gem2020 <- read_csv2("gem2020.csv")
strb2010 <- read_csv2("strb2021.csv")
But there are many more files in the directory and subdirectories. To read them all one by one is very tedious.
Now I have already experimented a little with the map function, but I have not yet figured out how to automatically generate the names of the dataframes from the file names.
A first simple try was:
lcl_forecast_data <- lcl_forecast_data_files %>%
map(
function(x) {
str_replace(basename(x), ".csv","") <- read_csv2(x)
}
)
But this did not work :-(
Is it even possible to generate names for dataframes like this?
Or are there other, simpler possibilities?
Greetings
