Dear R Helpers

(There is a small correction in my earlier mail. In the 'instrument.csv' file, I had mentioned only three columns. Actually there are 7 columns. I regret the error. Rest contents remains the same. Thanks)

I have an 'instrument.csv' file with?7 instrument names and 5 rates each i.e. it has 7 columns and?6 rows (including row names).

'instrument.csv'

instrument1????? instrument2???........???? instrument7
12???????????????????????? 5?????????????????????????? ?? 14
11???????????????????????? 7??????????????????????????????? 7
14???????????????????????11?? ??????????????????????????? ?3
? 8?????????????????????? 21????????????????????????????? 10
11???????????????????????? 3??????????????????????????????? 5


Following is my R code.

ONS = read.csv('Instrument.csv')
n = length(ONS)

Y = NULL
B = NULL

for (i in 1 : n)

?{

?Y[i] = ONS[i]

??for (j in 1 : length(Y[[i]]))
???{
???B[j] = (Y[[i]][j])^2
???}

?}

Problem is when I type B, I get the processed result only for the last column i.e. Y[7]. It doesn't store results for Y[1] to Y[7].

I need B[1], B[2].......upto B[7].

Please guide me how do I store individual column processed results?

Thanking you all in advance
