Calculating distance matrix for large dataset
Dear R users
I wondered if any of you ever tried to calculate distance matrix with very
large data set, and if anyone out there can confirm this error message I
got actually mean that my data is too large for this task.
negative length vectors are not allowed
My data size and code used
dim(mydata_nor)[1] 365000 144> d <- dist(mydata_nor, method = "euclidean")
Here my data has 1000 samples each has a year data observed by 10 minutes
interval daily, so the size is (365* 1000) * 144.
I checked the manual of function 'dist' but can not see the upper limit
size allow...
