[R] Error because of large dimension

Hi all, I am doing some calculation with very large dimension. I need to create a matrix with three columns and a very large number of rows (3195*1290*495*35*35*35*15=1.312083e+15) i n order to allocate calculation result from a for loop. R does not allow me to create such a matrix because of

Re: [R] Error because of large dimension

Hey Hanna, nrow and ncol in matrix() are integer-based, for the moment at least; accordingly they have a maximum value. (3195*1290*495*35*35*35*15) is actually larger than an integer can hold - you can test this with: str((3195*1290*495*35*35*35*15)) Which shows that it's stored as a numeric

[R] logical vector of the indices of a string in a vector

Hi, it might be trivial but is there any way to get the logical vector of the indices of a string in a vector? I thought that %in% would do but it doesn't. I also want to filter the empty fields. Here I want to extract the non-empty elements containing "Yes":x =c("Yes, fsd", "", "No","","Yes,

I think this mailing list is wonderful and it has helped me a lot. In fact, I am not sure I would be using R today if it was not for this list. Bob On 1/24/2016 4:42 PM, Michael Friendly wrote: On 1/23/2016 7:28 AM, Jean-Luc Dupouey wrote: Dear members, Not a technical question: But one

Re: [R] Error because of large dimension

FYI, the matrix you tried to allocate would hold (3195*1290*495*35*35*35*15) * 3 = 3.936248e+15 values. Each value would occupy 8 bytes of memory (for the double data type). In other words, in order to keep this data matrix in memory you would require a computer with at least 3.148998e+16 bytes

Re: [R] Extracting complete information from XML data file using R-Nested Lists

Hey Sowmiyan, I would recommend taking a look at the xml2, rather than xml, package for a start. It's a lot more structured and traversing between elements far easier :) On 24 January 2016 at 12:27, sowmiyan wrote: > I am working with a XML, which can be found in the
