Stacked Bar Plot in R

bar-chart, ggplot2, plot, r

Solution

The dataset:

dat <- read.table(text = "A   B   C   D   E   F    G
1 480 780 431 295 670 360  190
2 720 350 377 255 340 615  345
3 460 480 179 560  60 735 1260
4 220 240 876 789 820 100   75", header = TRUE)

Now you can convert the data frame into a matrix and use the `barplot` function.

barplot(as.matrix(dat))

Problem

I've looked at the similar questions on here regarding stacked bar plots in R, but I'm still not having any luck. I have created the following data frame: ``` A B C D E F G 1 480 780 431 295 670 360 190 2 720 350 377 255 340 615 345 3 460 480 179 560 60 735 1260 4 220 240 876 789 820 100 75 ``` A:G represents the x-axis and the y-axis would be duration (seconds). How would I go about stacking the following data in R? Thank you very much in advance for your time and help.
