R help - Aug 2010 - Help with Vectors and conditional functions

Good morning,

I have something like this: names(coint_tests) <- apply(b,2,paste,
collapse="_") which prints 15 names like: A_B, C_D, E_F, ...
AA,B,C,D.. Are time series. Then there is a vector called coint_tests of length
15 which yields "yes" or "no".

I need to add a function to plot the time series Ai_Bi if the coint_tests
vectors gives me a "YES".


I tried:    for (i in 1:(length(coint_tests))
                        if (coint_tests[[i]]="YES")
{plot(coint_tests[i])}

But it does not work. I would most appreciate if someone could give me some
insight as to how to sort this out. Thank you

Hi,

I haven't spent too much time on it, but that might help:
if (coint_tests[[i]]=="YES")...
Note the double "=" which is the operator for equality. The single
"="
is the assignment operator, especially with arguments.

HTH, Ivan
