R help - Feb 2007 - Angle of Bar Plot

Hello everyone,

I want to use 'angle' in Bar Plot with different angles for different
bars.

For example if the 3th column of the following data is '0.0', I want the
angle to be '45' degrees, if it is '1.92', I want '65'
and …



1     3.74    0.00

2     6.12    1.92

3     9.71    0.00

4     1.32    1.92

5     8.24    4.48


Thanks,

 couldn't read the end of your e-mail but chose to set angle=80
for the third value ...

z <- matrix(c(3.74,0,6.12,1.92,9.71,0,1.32,1.92,8.24,4.48),byrow=TRUE,
+ ncol=2)
> z
     [,1] [,2]
[1,] 3.74 0.00
[2,] 6.12 1.92
[3,] 9.71 0.00
[4,] 1.32 1.92
[5,] 8.24 4.48
> barplot(z[,1],angle=c(45,65,80)[as.numeric(factor(z[,2]))],density=5)
  I will point out that this is pretty ugly though ...
