Question

I have four datasets, a sample can be found here, all of them have four columns and same column names. But I just want to plot 1st column on x axis and last column on y axis, and I want to plot all of them on one Master plot on four equal areas,
like the image below.

How can I achieve that ?

Here’s one solution using par.

(I read your file Ratio_J_B5H2.csv into R as data frame dat.)

Create a 2 x 2 window for the plots:

par(mfrow = c(2, 2))

Now, you could create four plots:

barplot(dat[,4], names.arg = dat[,1])
barplot(dat[,4], names.arg = dat[,1])
barplot(dat[,4], names.arg = dat[,1])
barplot(dat[,4], names.arg = dat[,1])
