how to plot histogram with the first column value as x and the second column as y value?

I have the following structure in a file:

2014  50
2012  60
2016  80

I wish to plot a histogram using the first column as x values, and the second column as y values.

I tried:

data<-read.table(fileinput.txt, header = T)
hist(data[,2])

but it only gives me two bars.

If I want to write this into an R script, how to save the image to a location on the server?

barplot(dt$obs,dt$year)

Have a look at the other arguments as well.

You can use jpeg to save it to a file.
