R help - Oct 2013 - Need help with plotting the graph

Hello All,

The version of R I am using is as follows
> version
               _
platform       x86_64-pc-linux-gnu
arch           x86_64
os             linux-gnu
system         x86_64, linux-gnu
status
major          2
minor          14.1
year           2011
month          12
day            22
svn rev        57956
language       R
version.string R version 2.14.1 (2011-12-22)


I just few days back started using R for basic statistical analysis. I
want to plot the graph of following information

> df
                  disk vmfs  vmdk     IOPS       BW
1 naa.5000a7203007ed8f    3 eager 16886.77 65.96393
2 naa.5000a7203007ed8f    3  lazy 44623.15 174.3092
3 naa.5000a7203007ed8f    5 eager 16767.53 65.49815
4 naa.5000a7203007ed8f    5  lazy 45891.55 179.2639
> str(df)
'data.frame':    4 obs. of  5 variables:
 $ disk:List of 4
  ..$ : chr "naa.5000a7203007ed8f"
  ..$ : chr "naa.5000a7203007ed8f"
  ..$ : chr "naa.5000a7203007ed8f"
  ..$ : chr "naa.5000a7203007ed8f"
 $ vmfs:List of 4
  ..$ : num 3
  ..$ : num 3
  ..$ : num 5
  ..$ : num 5
 $ vmdk:List of 4
  ..$ : chr "eager"
  ..$ : chr "lazy"
  ..$ : chr "eager"
  ..$ : chr "lazy"
 $ IOPS:List of 4
  ..$ : num 16887
  ..$ : num 44623
  ..$ : num 16768
  ..$ : num 45892
 $ BW  :List of 4
  ..$ : num 66
  ..$ : num 174
  ..$ : num 65.5
  ..$ : num 179

I would like Y axis to represent BW and X axis to represent disk, vmfs and vmdk.

All the examples in books or online have single X axis. I could not
find an example which does something similar to what I am trying. Can
anyone please give me some pointers?

Thanks and Regards,
Prasad

First. You should update R to the latest version, 3.0.2.

Second. What commands have you tried and what error messages did
you receive?

Third. Use dput(df) and send the output to the mailing list. A
data frame usually consists of several vectors, not several
lists. It might be necessary to explain how you created or
obtained df.

Hi Prasad,
You may want something like the following:

df<-read.table(
  text="disk vmfs  vmdk     IOPS       BW
  naa.5000a7203007ed8f    3 eager 16886.77 65.96393 

  naa.5000a7203007ed8f    3  lazy 44623.15 174.3092
  naa.5000a7203007ed8f    5 eager 16767.53 65.49815
  naa.5000a7203007ed8f    5  lazy 45891.55 179.2639",
  header=TRUE)
x11(width=10,height=5)
par(mfrow=c(1,3))
brkdn_disk<-by(df$BW,df$disk,FUN=mean)
plot(brkdn_disk,xaxt="n")
axis(1,at=1:length(brkdn_disk),labels=names(brkdn_disk))
brkdn_vmfs<-by(df$BW,df$vmfs,FUN=mean)
plot(brkdn_vmfs,xaxt="n")
axis(1,at=1:length(brkdn_vmfs),labels=names(brkdn_vmfs))
brkdn_vmdk<-by(df$BW,df$vmdk,FUN=mean)
plot(brkdn_vmdk,xaxt="n")
axis(1,at=1:length(brkdn_vmdk),labels=names(brkdn_vmdk))

You can also have the plots in a vertical format by using:

par(mfrow=c(3,1))
