Arguments
fname |
String with the file name that contains the binary data. |
extrownames |
A vector of RStrings with the names of the rows to be extracted. If the binary file has no row names, or _any_ of the row names is not present, an empty matrix is returned. |

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")
Rf[c("A","C"),]
vf<-GetJManyRowsByNames(tmpfile1,c("A","C"))
