DfReadDataFile | R Documentation |
Read a disk file and create a 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 specified below. |
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 the iMRMC
format is actively
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.
