Question

I want to create a barplot and my data is in a csv file in the following format

0,22
40,50
80,62
120,70
160,62
200,49
240,52
280,64
320,57
360,50
400,47
440,52
480,73
520,70
560,68
600,71
640,69
680,61
720,59
760,59
800,62
840,62
880,62
920,72
960,81
1000,89
1040,86
1080,76
1120,80
1160,95

The element before the comma should be the position in the x axis and the element after the comma the height= of the bar at that position. I can do this in Excel but the data is large.
The graph I want would look like this.

I have tried the following but I think it sums the data in each row.

data <- as.matrix(read.csv(file="data.csv",sep=",",header=FALSE))
barplot(data)

Answer 1

barplot(x$V2, names.arg = seq_len(nrow(x)), cex.names = .6)
