Histogram from a table in R

[gina_alessa]

Hi all,

I am new in R. I am trying to make an histogram but I can't figure it out.
I have .cvs table with a lot of data that look like this: I already have the frequency of each interval (Counts).

Interval   Counts
00:19           0
10:19          3117
20:29         4500
30:39         2330.......

I want to make the histogram with that. At the y axis I want to have the Counts and at x axis I want to have the intervals.

Thanks in advanced!!!

Possibly barplot() is what you are after.

?barplot

HTH ....

intv = c('0-19','10-19','20-29','30-39')
cnts = c(0, 3117, 4500, 2330)
barplot(cnts, space=0, names = intv, xlab='Age Range', ylab = 'Counts',
main='My Histogram')
