[R] 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.
