dataframe - what is the best way to visualize a table on graph in r -

-

i have following table(data frame):

             week24  week25 week26  under 0.5m    1824   1878   1955  0.5 1m     170    205    211  1to3          117    109    124  3to6           19     19     25  6to10           9      8      8  10to15          4      3      5  15to30          9     13      9  above 30m      19     32     28

i looking best way visualize on graph can have row names under 0.5m:above 30m in x axis .

i have tried barplot() results not good

how can make more informative?

it's not clear me trying obtain. maybe adding legend graph way more descriptive. i've simple data frame show mean:

df <- data.frame(z=c(1,2,3),y=c(2,3,1)) row.names(df) <- c("cat1","cat2","cat3")  barplot(as.matrix(df),         legend.text = row.names(df),         args.legend = list(x = "right"),         col = c("blue","green","red"))
