DfReadDataFile | R Documentation |
Read an Excel file and create an ROC, FROC or LROC dataset object from it.
DfReadDataFile(
fileName,
format = "JAFROC",
newExcelFileFormat = FALSE,
lrocForcedMark = NA,
delimiter = ",",
sequentialNames = FALSE
)
fileName |
A string specifying the name of the file. The file-extension
must match the |
format |
A string specifying the format of the data file. It can be
|
newExcelFileFormat |
Logical. Must be true to read LROC data. This
argument only applies to the |
lrocForcedMark |
Logical: For LROC dataset only: is a forced mark
required on every image? The default is |
delimiter |
The string delimiter to be used for the |
sequentialNames |
A logical variable: if |
A dataset with the structure specified in
RJafroc-package
.
The "MRMC"
format is deprecated. For non-JAFROC formats four
file extensions (.csv
, .txt
, .lrc
and .imrmc
)
are possible, all of which are restricted to ROC data. Only iMRMC
format is now supported, i.e, files with extension .imrmc
. Other
formats (.csv
, .txt
, .lrc
) are deprecated. Such files
can still be read by this function and then saved to a JAFROC format file
for further analysis within this package.
For non-JAFROC data file formats, the readerID
and
modalityID
fields must be unique integers.
This function is used only for factorial datasets. For SPLIT-PLOT datasets use function DfReadSP.
