Re: [R] finding big matrix size and SVD

I have 500,00 rows in my matrix and i was wondering whether there is any way to get its SVD without breaking it to parts because if R can only read about 1000 columns then to have a rectangular matrix (diagonal i think they are called) I will need to have only 1000 rows I want to know how i

[R] reshape matrix entities to columns

Greeting R helpers J I am not familiar with R but I have to use it to analyze data set that I have (30,000 20,000) I want to change the structure of the dataset and I am wondering how that might be possible in R A main data looks like this: some entities are empty AgeNo. Age

Re: [R] reshape matrix entities to columns

I changed it so i hope it will look better now the matrix is like this: AgeNo. Age No. AgeNo. Center1 52 8 7 Center210 720 9 4 10 column name = sequence of age-no. But what I want the data to

I am sending this again as they told me that the data was unreadable, so really hope that this will work...so sorry all note: matrix contains a lot of empty entities Greeting R helpers I am not familiar with R but I have to use it to analyze data set that I have (30,000 20,000) I want to
