I am running into some problems performing a multidimensional scaling image. First of my dataset is quite large (330.000 fields: 33000 rows, 10 columns). The output image needs to contain 10 dots, 1 for each column. The fields in the dataset contain intensity values which first need to be converted to a distance matrix, however when doing so I run into a memory limit in R.
I was hoping you could help solve this problem or perhaps point me to a program that can handle these kind of data sizes.
