Dear all I have a simple R question. How do I execute R-code stored in a variable? E.g if I have a variable which contains some R-code: c = "reg <- lm(sales$sales~sales$price)" Is it possible to execute c E.g like Exec(c) I hope someone can help. Thank you Kim Lillesøe [[alternative HTML version deleted]]
Hi Kim, You can use eval(parse(text = c)) Best, Ista On Tue, Aug 2, 2011 at 8:22 AM, Kim Lilles?e <kli at dataminds.dk> wrote:> Dear all > > I have a simple R question.

Yes, you can use:
eval(parse(text=c))
On the other hand I would not recommend to use c as a variable name as it is the
name of a very important function in the R language to aggregate data.

Dear all
I have a simple R question. How do I execute R-code stored in a variable?
E.g if I have a variable which contains some R-code:
c = "reg <- lm(sales$sales~sales$price)"
Is it possible to execute c
E.g like Exec(c)
I hope someone can help.
Thank you
