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.
If you data frame is called 'df'
df$PRODUCTS[df$PRODUCTS 70] - NA

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?

say your data frame is called
condition1 | condition2 (or)
condition1 condition2 (and)
tmp$PRODUCTS[tmp$PRODUCTS 70 | tmp$PRODUCTS 20] - NA
