Description Usage Arguments Value Author(s) See Also Examples

Reads a dChip CDF.bin file.

Please note that this method is incomplete as it currently doesn't read all fields. It is only made available so that someelse can continue the development.

1	readCdfBin(con, units=NULL, ...)

`con`	A `connection` or a `character` filename.
`units`	An `integer` `vector` specifying the units to be read. If `NULL`, all units are read.
`...`	Not used.

Returns a list structure containing the file header and the unit data.

Henrik Bengtsson

To read only the CDF.bin file header, see readCdfBinHeader().

path <- system.file("exData", package="dChipIO")
chipType <- "Test3"
filename <- sprintf("%s.CDF.bin", chipType)
pathname <- file.path(path, filename)

hdr <- readCdfBinHeader(pathname)
print(hdr)

data <- readCdfBin(pathname)
str(data)

# Read a subset of the units
units <- c(10:11, 15:20, 150:105, 2,2,2)
dataT <- readCdfBin(pathname, units=units)
str(dataT)

# Assert correctness
for (ff in c("unitNames", "numProbes", "CellPos")) {
  stopifnot(length(dataT[[ff]]) == length(units))
  stopifnot(identical(dataT[[ff]], data[[ff]][units]))
}
