readGCTX {slinky} | R Documentation |
Read portions of data matrix from LINCS gctx datafile
readGCTX(x) ## S4 method for signature 'Slinky' readGCTX(x)
x |
a Slinky Object |
Matrix of expression data with rownames and
colnames appropriately set. If a subset of the data is desired,
subset the slinky object itself, not the resulting data matrix.
That is, data <- readGCTX(x[1:50,1:500])
will be
MUCH faster than ndata <- readGCTX(x)[1:50, 1:500]
.
