[R] Conditional ploting with logical vector

series by comparing the values at the single time points by a t-test. I know this is probably not the correct way to compare the whole series, but I have to do it this way ('constraints'). The question is: do I have to adjust for multiple testing by e.g. Bonferroni correction? -- Armin Goralczyk

I am sorry if some questions may sound weird but I am just beginning to understand this (for me) rather complex concept. Thanks for any help. -- Armin
