RStudio: Is there any way to get a data frame to show the column number using the View() function?

I've searched on google, here and on youtube but I've not seen anyone ask this, thus I doubt it is possible. But I have a data frame with a decent number of rows (25) and I'm making a correlation plot between the numerical variables and a heat map of Chi-Squared Test p-values between the categorical variables.

To do so I need to refer to the column ID for each relevant variable. I'm just wondering if there is a way to make the View() function display column numbers by default, similar to how there is an index column for row numbers.

Thank you for your time

You could label the columns, as View displays labels:

library(labelled)
var_label(iris) <- as.list(setNames(as.character(1:ncol(iris)),colnames(iris)))
View(iris)

Here is an option:

set.seed(42)

# example dataframe
df_0 <- data.frame(x = rnorm(3),
                   y = rnorm(3),
                   z = rnorm(3))
# copy to leave original copy intact
df_1 <- df_0
# rename columns with indices
colnames(df_1) <- 1:ncol(df_1)
# produces
df_1
#>            1          2           3
#> 1  1.3709584  0.6328626  1.51152200
#> 2 -0.5646982  0.4042683 -0.09465904
#> 3  0.3631284 -0.1061245  2.01842371

View(df_1)
