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
Dear R helpers
I have a big data sheet (CSV) which I use âread.csvâ to read it
When im trying to get the Dim() it says 38 column which is not correct it
should
be something about 400.
I am wondering whether there is any way I can read it right⦠I have used
ncol()
and itâs the same

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
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
