Re: [R] substitute variable

2007-03-26 Thread Sergio Della Franca 
Ok, this run correctly.

Now i want to perform much more conditions, i.e.:

tmp$PRODUCTS[tmp$PRODUCTS > 70] <- NA

and

tmp$PRODUCTS[tmp$PRODUCTS < 20] <- NA.

How can i perform this double condition in the same code?

[R] substitute variable

2007-03-26 Thread Sergio Della Franca 
Dear R-Helpers,

I want to substitute the contents of a variable under some contitions.

I.e., I have this data set:

YEAR   PRODUCTS
1  80
2  90
3  50
4  60
5  30

I want to perform this condition:
if products> 70 then products=NA else products=products.

I'd like to achive the seguent result:

 YEAR   PRODUCTS
1  NA
2  NA
3  50
4  60
5  30
How can i develop this?


Thank you in advance.
