Thanks Jim for your efforts. The code you gave works for me if I
include df <- read.table() line.
Since I am kind of new to R, I think I am not being efficient with the
data.frame df.

structure(list(disk = list("naa.5000a7203007ed8f", "naa.5000a7203007ed8f",
"naa.5000a7203007ed8f", "naa.5000a7203007ed8f", "naa.5000a720300895c4",
"naa.5000a720300895c4", "naa.5000a720300895c4", "naa.5000a720300895c4"),
vmfs = list(3, 3, 5, 5, 3, 3, 5, 5), vmdk = list("eager",
"lazy", "eager", "lazy", "eager", "lazy", "eager", "lazy"),
IOPS = list(16886.766301, 44623.145983, 16767.526886, 45891.547436,
16794.495655, 45289.670722, 16603.198764, 46092.4011),
BW = list(65.963931, 174.309164, 65.498152, 179.263857, 65.603499,
176.912776, 64.856245, 180.048442)), .Names = c("disk",
"vmfs", "vmdk", "IOPS", "BW"), row.names = c(NA, -8L), class = "data.frame")
I will find the way to correctly represent the result dataframe.
Any ways thanks Jim for your reply.
Thanks and Regards,
Prasad
