Dear R Helpers
 
I have an 'instrument.csv' file with 3 instrument names and 5 rates each i.e. it has 7 columns and 6 rows (including row names).
 
'instrument.csv'
 
instrument1      instrument2           instrument3
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
 
Regards
 
Madhavi
