Phoebe,
In addition to the barplot method below, you really can use plot() to
draw what it sounds like you are looking for IF you have a categorical
variable. To illustrate, try running the following code:
x=sample(c("Richard", "Minnie", "Albert", "Helen", "Joe", "Kingston"),
50, replace=T)
x=as.factor(x)
plot(x)
See also ?plot.factor

Hi Phoebe,
Try
x <- c(12, 33, 56, 67, 15, 66)
names(x) <- c('Richard','Minnie','Albert','Helen','Joe','Kingston')
barplot(x, las = 1, space = 0)
HTH,

Hi,
Can someone tell me how to draw a histogram for the following
summary?
Richard Minnie Albert Helen Joe Kingston
12 33 56 67 15 66
The summary tell that Richard has occurrence 12, Minnie has
occurrence 33,
and so on. I would like to view this summary in a histogram.
I want the X-axis be the person name (Richard, Minnie, ....), Y-
axis be the
frequency (12, 33....).
How can I make the histogram has 6 bars, each bar was named as
Richard,
Minnie, ... , Kingston?
Thanks,
Phoebe
