Re: [R] assigning dimnames to arrays

Thanks, Bill. Sooo... taking the error literally, temp1 = array(NA, c(3,2,1)) dimnames(temp1)[[3]] = list( "test" ) works, even though mode( dimnames(temp1)[[3]] ) yields "character". Setting all the dimension names simultaneously still feels way better. -- Sent from my phone. Please

Re: [R] assigning dimnames to arrays

It happens because dimnames(originalArray) is NULL and when [[<- extends NULL it turns it into a list if the size of the new element is not one but into a vector with the type of new element if the new element's size is one. > str( `[[<-`(NULL, 3, value="One") ) chr [1:3] NA NA "One" > str(

Re: [R] assigning dimnames to arrays

While I generally agree that it is better to design code that sets all of the dimension names simultaneously, the discrepancy between behavior when the dimensions are longer than 1 and when they are equal to 1 seems irregular. Someone went to some lengths to make it possible to set dimnames

Re: [R] Issue with subset in glm

When you use the data= argument in glm(), the function looks in the data.frame for a variable first. You have created two versions of stype, one in the data.frame and one outside it. So your first glm() selects all the cases apistrat since apistrat$stype always equals apistrat$stype. You can

You can use wrapnls from the nlmrt package to get an nls object. Run it instead of nlxb. It runs nlxb followed by nls so that the output is an nls object.. Then you can use all of nls' methods. On occiasion that fails even if nlxb succeeds since the nls optimization can fail independently of
