I’m having a dataframe as like below.
> avg_data
date region AveElapsedTime
1 5/1/2012 preprod 23
2 5/2/2012 prod 76
3 5/3/2012 Beta 34
4 5/4/2012 prod 30
5 5/5/2012 Beta 22
6 5/6/2012 preprod 32
7 5/7/2012 Beta 21
8 5/8/2012 prod 44
9 5/9/2012 preprod 45
10 5/10/2012 Beta 23
11 5/11/2012 prod 50
12 5/13/2012 Beta 26
13 5/14/2012 preprod 33
14 5/15/2012 Beta 75
15 5/16/2012 preprod 56
16 5/17/2012 Beta 32
17 5/18/2012 preprod 67
18 5/19/2012 prod 40
When I use the cbind, it is not giving the right row numbers..
> cbind(avg_data[avg_data$region == "preprod", "date" ], avg_data[avg_data$region == "preprod", "AveElapsedTime" ])
[,1] [,2]
[1,] 3 23
[2,] 15 32
[3,] 18 45
[4,] 5 33
[5,] 7 56
[6,] 9 67
This is giving problem while plotting the graph. I’m having date as x axis and AveElapsedTime value as Y axis. Instead of starting the first plot from 5/1/2012, it is starting from 5/3/2012 and trying to plot based on the rownumber given above.
If it displays as like below, then the graph will display correctly.. Please advise..
Rownumber AveElapsedTime
[,1] [,2]
[1,] 1 23
[2,] 6 32
[3,] 9 45
[4,] 13 33
[5,] 15 56
[6,] 17 67
Here is my code.. which is working now.. Need to change the color for the lines..
avg_data <- read.table("qes.tbl", header=T, sep=",")

lines(dl, type="l", pch=2, col=plot_colors[num])

}

drawGraph(avg_data, lab, MTitle, 5)
It seems like you are asking for just the rownumbers as the first column. If that is so:
If you also want to rename the columns in the process:
