[R] Creating a histogram from a frequency vector

[Rui Barradas]

Hello,

Here are 3 ways.

The first are almost the same, they use base graphics.

x <- 1:6
y <- c(73,53,42,67,41,50)

barplot(setNames(y, x))

Or

names(y) <- x
barplot(y)


And 3:

library(ggplot2)
ggplot(data.frame(x, y), aes(x, y)) +
   geom_col()


Hope this helps,

Rui Barradas

> I have a vector like say 73,53,42,67,41,50 where these numbers are the number of occurrences of the data values 1,2,3,4,5,6 - so in essence I have the frequency bit from the hist() function.  I can't see an elegant way (there are clearly messy workarounds like generating a vector of 73 1's, 53 2's etc) of creating a histogram from this data set.  Is there one?
