How to make a data frame with function in R?
For some basic publications I have to make almost same codes for many tables. So I have to make a quite fast code to make data frames from files and to make some same operations with data using only one same formula.
Example:
# Creating function
basic_sum <- function (place, DF, factor_col, sum) {
# Uploading data.frame
DF <- read.csv (place, sep = ";")
# Converting to factor
for (i in factor_col) {
DF [, i] <- as.factor (DF [, i])
}
# Summary
sum <- summary (DF)
View (sum)
}
Than I'm running that code and get a function basic_sum
If I want to work with my Data I call this function with arguments:
basic_sum (place = "~/DataFrame.csv", DF = DataFrame,
factor_col = c (1, 6 : 11), sum = DF_sum)
After running it nothing happens. I mean, I don't have anything new in Environment. No new data, no new vars or something else.
In my thoughts it seems that finally I have to get:
1) data.frame "DataFrame", that was uploaded DataFrame.csv;
2) 1st, 6th, 7th and all other columns until 11th will be factor
3) data.frame "DF_sum" with summary of all my columns from "DataFrame"
4) I will see data.frame "DF_sum".
Well, I see all of it in console, but I need it in Environment and to save it somewhere.
Seems that I'm doing something wrong... But I don't know what.
P.S.: If I try to run it without function (of course replacing DF to DataFrame, factor_col to с (1, 6 : 11) and so on...) everything is all right. But I have to rewrite code every time or at lest replace all DF and other that bother me.
With great regards,

Try addingreturn(sum)as the last line of the function. R will return the last line of a function by default, and right now the last line isView, which does not return any values.
