This is not a problem, but I thought that I might say one or two things in favour of right pointing assignment before anybody influential gets the idea of scrapping it! Situation (a) You have just typed a long complcated expression into the console and you suddenly realise that you will need it later in the session. Just append - something to the end of the expression. You can do this with any recently evaluated expression with the help of the up-arrow key (in Windows at least). Situation (b) You have written a chunk of code and you want to see how it behaves for various values of the scalar fred. Just put - fred at the start of the code block, type any number, then paste the code into the console.

This is not a problem, but I thought that I might say one or
two things
in favour of right pointing assignment before anybody
influential gets
the idea of scrapping it!
Situation (a)
You have just typed a long complcated expression into the console and
you suddenly realise that you will need it later in the session. Just
append
- something
to the end of the expression. You can do this with any recently
evaluated expression with the help of the up-arrow key (in Windows at
least).
You can do this just as easily in two ways:
1. IforgotThis - .Last.value [This always works, even if command editing
is not available.]
2. If command line editing is available, hit [up-arrow], [home] (or ctrl-a)
then type IforgotThis = ...
Situation (b)
You have written a chunk of code and you want to see how it
behaves for
various values of the scalar fred. Just put
- fred
at the start of the code block, type any number, then paste the code
into the console.
This is also easily accomodated w/o the use of -: Instead of
MyValue - fred
[code that follows]
use:
fred -
MyValue
[code that follows]

So instead of 3 paste 8 paste etc you need to do fred - 3 paste fred - 8 paste etc Not a big saving, but some of us are lazy! -- Dr Murray Jorgensen http://www.stats.waikato.ac.nz/Staff/maj.html Department of Statistics, University of Waikato, Hamilton, New Zealand Email: [EMAIL PROTECTED]Fax 7 838 4155 Phone +64 7 838 4773 wk+64 7 849 6486 homeMobile 021 1395 862 __ [EMAIL PROTECTED] mailing list https://www.stat.math.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html
