compatible among incompatible platforms. It is ASCII format and can 
even be E_Mailed.

 REAL 
 
 

REAL {Fx}
This command extract the real part of the current the data set 
considered as complex.
On 2D and 3D you can choose on which axis the REAL operation will be 
taken. Data size can thus be reduced either by 2 , 4 or even 8.

 REF 
 
 

This command will force a new computing of the display, as if a 
display command had been issued. This is useful for cleaning the 
spectrum after any command that draw on the spectrum, such as POINT, 
SHOWLINE, etc...

 REF3D 
 
 

This command will display a 3D view of the current 3D data-set, in 
the window previously opened with the DISP3D command. The parameters 
used for the display can be chosen with the DISP3D? and the CHECK3D 
commands.

see also : CHECK3D DISP3D

 
 REFMACRO 
 
 

        When this context is set to 1 the program refreshes the on-
screen display during macro execution, this permits to follow the 
data during the program execution, but slows down the macro 
execution.
	When equal to 0, the display is refreshed only at the end of the 
macro execution. Default value is 0.

 RELAXRATE 
 
 

Compute the relaxation rate (in arbitrary unit) from the last LP 
analysis.

 rem_h2o -no param-

 this macro will remove most of water signal (large zero-frequency
 signal) by fitting and removing the water FID in the time domain

 used in 1D, will overflow the 2D area !!

 to be used before any processing, on the FID.


 
 RESIDUE 
 
 

Returns into the current buffer the result of the substraction of 
the DATA buffer, with the reconstruction of the mock data from the 
spectrum held into the current buffer. To be used after a MaxEnt run 
to see that part of the signal not analysed by the MaxEnt process.

 REVERSE 
 
 

REVERSE {Fx} 
reverse the order of the current data-set (i.e. first points are 
last, last points are first).
If dataset is complex, REVERSE will reverse the complex  vector (2 
by 2).

 REVF 
 
 

REVF {Fx}
   Processes FID data-sets by multiplying by -1 2 points out of 4. 
Permits to preprocess Bruker FIDs in Dim 2 (Bruker trick) before 
RFT, or permits to bring back zero frequency in the center for some 
other data formats

 ROW 
 
 

ROW n
Extract the nth 1D row (along F2) from the 2D data-set, and put it 
in the 1D buffer. The row will be available as a 1D data set when 
going from 2D to 1D

roots expected.
