GetJNames: GetJNames

In jmatrix: Read from/Write to Disk Matrices with any Data Type in a Binary Format

GetJNames

Description

Returns a R list of two elements, rownames and colnames, each of them being a R StringVector with the corresponding names

Usage

GetJNames(fname)

Arguments

fname

String with the file name that contains the binary data.

Value

N["rownames","colnames"]: A list with two elements named rownames and colnames which are R StringVectors. If the binary file has no row or column names as metadata BOTH will be returned as empty vectors, even if one of them exists. If you want to extract only one, use either GetJRowNames or GetJColNames, as appropriate.

Examples

Rf <- matrix(runif(48),nrow=6)
rownames(Rf) <- c("A","B","C","D","E","F")
colnames(Rf) <- c("a","b","c","d","e","f","g","h")
tmpfile1=paste0(tempdir(),"/Rfullfloat.bin")
JWriteBin(Rf,tmpfile1,dtype="float",dmtype="full",comment="Full matrix of floats")
N<-GetJNames(tmpfile1)
N["rownames"]
N["colnames"]
