r - Attempting barplot -


hi trying create beside barplot bars not in correct spaces appear overlapping.

barplot(counts,      main ="2011 vs 2016 men volunteering",     ylim=c(0,320000),     xlab="age (years)",     ylab = "frequancy",     names.arg = c("15-19", "20-24", "25-34", "35-44", "45-54", "55-64", "65-74", "75-84", "84 , over"),     col=c("red","green"),     beside=true)  legend("topright",         legend = c("2011", "2016"),         fill = c("red", "green"))

outputting this:

when in reality want this:

i have tried using ncol = 2 can't work, how implement it?

like this,

barplot(counts,      main ="2011 vs 2016 men volunteering",     ylim=c(0,320000),     xlab="age (years)",     ylab = "frequancy",     names.arg = c("15-19", "20-24", "25-34", "35-44", "45-54", "55-64", "65-74", "75-84", "84 , over"),     ncol = 2,     col=c("red","green"),     beside=true)  legend("topright",         legend = c("2011", "2016"),         fill = c("red", "green"))

or this?

counts <- as.matrix(elevenmenvolunteerage, sixteenmenvolunteerage, ncol = 2)

all appreciated thank much.

as there no reproducible data counts, including few examples on how dodged plots can created.

ggplot(mtcars, aes(factor(cyl), fill = factor(vs))) +     geom_bar(position = "dodge")

enter image description here

# grouped bar plot counts <- table(mtcars$vs, mtcars$gear) barplot(counts, col=c("darkblue","red"),         legend = rownames(counts), beside=true)

enter image description here
