Plotting a set of points with no specified x-values in the data

[tchntm43]

I have a data frame that is only a single column of values 1-100 each. I want to plot these (using geom_point) such that y = the values in the column, and x is just the order of the values in the column (i.e. for the first value in the column, x = 1, second value x = 2, etc.). I could mutate in another column called index that just adds an index number for each observation, but is there a way to do it without doing that? Like, if I want to leave the data intact as just one column?

I believe setting x = 1:nrow(df) produces your desired outcome.

library(tidyverse)
set.seed(44)

df = data.frame(A = sample(1:100, 100, TRUE))

ggplot(df, aes(x = 1:nrow(df), y = A)) + 
  geom_point()
