Maybe I can help if I can see the code, just the few lines that do the loop.

You need to generate a new matrix with interpolated values.

So first You will need to define the new matrix:

If your matrix is named "nm" then:

x=length(nm[1,])

y=length(nm[,1])

new_matrix=matrix(ncol=x,nrow=y)

for (i in 1:x)

{

new_matrix[,i]=interpolation_function(nm[,i])

}

I don't know , but if the interpolation function is used over full matrix and returns a matrix,

then You have to use

new_matrix=interpolation_function(nm)

instead of the upper rows.

i like ths

I tried using the following code... and it was working well..... approx is the function used for interpolation method...

X = matrix(0,nrow(10),ncol(10));

for(i in 1:length(data))

{

X[i,i]

thank you Valeriya Simeonova for ur code... i Like it

You are welcome :)

can anyone suggest me where i am going wrong.. as Approx function is working fine... i have values in X .. but when i write the values in the text file it is giving me this error::

"Error in data.frame(x = list(x = c(1, 2.00668151447661, 3.01336302895323, :

arguments imply differing number of rows: 450, 20"

for(i in 1:7)

{

X[[i]]

i got the solution for my last post...

"Error in data.frame(x = list(x = c(1, 2.00668151447661, 3.01336302895323, :

arguments imply differing number of rows: 450, 20"

.. but still I would like to discuss more of R and making efficient programing......

thank you
