set the first row as headers in r

To set the first row as headers in R, you can use the header = TRUE argument when importing the data or create a data frame with custom headers.

Here is an example of setting the first row as headers when importing a CSV file:

main.r
my_data <- read.csv("my_file.csv", header = TRUE)
50 chars
2 lines

Alternatively, you can create a data frame and manually assign the headers like this:

main.r
my_data <- data.frame(col1 = c(1, 2, 3),
                      col2 = c("a", "b", "c"),
                      col3 = c(TRUE, FALSE, TRUE))
colnames(my_data) <- c("Header1", "Header2", "Header3")
195 chars
5 lines

Both of these options will set the first row as headers in the resulting data frame.
