Re: [R] Creating a conditional lag variable in R

Hi Faradj, There is a problem with your structure statement in that the hyphen (-) following the left angle bracket (<) has been transformed into a fancy hyphen somewhere in the process. I replaced it with an ordinary hyphen and it worked okay. Also, your coding for "B" seems to include the first y

[R] Creating a conditional lag variable in R

Dear R-users, I’ve a rather complicated task to do and need all the help I can get. I have data indicating whether a country has signed an agreement or not (1=yes and 0=otherwise). I want to simply create variable that would capture the years before the agreement is signed. The aim is to see

Re: [R] "rgb()" problem

Sorry, I meanwhile realized -- specifying rgb(255, 128, 128, alpha=0.5*255, maxColorValue=255) and rgb(1.0, 0.5, 0.5, alpha=0.5, maxColorValue=1) gives you (virtually) identical results, i.e., you need to also specify the "alpha" parameter in the range given by the "maxColorValue" argument.

Hi all, I would like to introduce you to a new package available on CRAN for performing meta-analysis of dose-response relationships, 'MBNMAdose'. For anyone who has performed a meta-analysis or network meta-analysis before, you might be aware of the difficulties of including different doses of a

[R] "rgb()" problem

Hi, I experienced a problem with the "rgb()" function. These two calls should (and do) return identical results: rgb(255, 128, 128, maxColorValue=255) rgb(1.0, 0.5, 0.5, maxColorValue=1) However, when I specify a non-default "alpha" channel (a "transparent" colour), I get differing results:
