[sage-support] Re: errors when defining R functions

[Emmanuel Charpentier]

I get normal error detection.

In a worksheet (in 'r' mode) :

bar-function(x) {
y-x+3)
return(y)
}

gives :

Erreur : ')' inattendu(e) in:
bar-function(x) {
y-x+3)
Erreur : objet 'y' introuvable
Erreur : '}' inattendu(e) in }


In a terminal :

charpent@asus16-ec:~$ sage -R

 bar-function (x) {

Erreur : ')' inattendu(e) in:
bar-function (x) {

As William said, an example is necessary...

 Hi
 I have noticed that when I'm in R mode and when define R functions 
 sometimes sage doesn't display errors if there are any. It just doesn't 
 define the function.

 Has anyone else noticed this? Is there anything I can do to get sage to 
 display the errors. It is hard to debug code when sage doesn't tell you 
 where is the problem.

 thanks
 F

[sage-support] How to extract value from array

[Santanu Sarkar]

Following code  I want to assign a value.


var('a,t,x')
T=[t==1, a==2]

Now I want to make x=t which is 1 in this case.
That is x will be 1.
