R help - Oct 2011 - Plot complete dataset

Hello,

     I am a new user of R, so I still have some basic difficulties.
    I'm trying to create a bar graph completely from reading a file.
   The idea was on the x axis have the columns of the table
Married ,Single,Divorced, widower
 the legend Ages
18-34
35-45
46-64
65-69
70-74

the dataset
dataset
   Ages Married Single Divorced widower
1 18-34    10.5   35.7      8.5     3.2
2 35-45    12.4   22.4     22.2    12.6
3 46-64    25.4   22.2     33.4    12.4
4 65-69    36.7   31.4     12.4    35.2
5 70-74    26.4   15.1      8.5    43.2


The code for barplot 

barplot(dataset,dataset$Single, col = c(rainbow(dataset$Ages)), legend
rownames(dataset$Ages), ylim = c(0, 100))

but I am not able to resolve.

Thanks

You should go back and read the help for barplot.  Do you really want to plot
the whole dataset (say as a stacked barplot)? Then something like this should do
it.

barplot(as.matrix(dataset[,2:5]),  col = c("lightblue",
"mistyrose", "lightcyan",
                "lavender", "cornsilk"), 
  legend = dataset$Ages, ylim = c(0, 100))

Your values don't add to 100, so I'm not sure what you actually want. 
If this isn't what you want then give us more information.


Hope this is helpful,
