[R] Referencing a component of a large object (Error: slot NULL)

reproducible code, however, I obtain this object through the package 'mi' and is computationally intensive. I'm not sure if it makes it easier for folks. Let me know. Any ideas? -- Andrea Lamont, PhD Post-Doctoral Fellow University of South Carolina Columbia, SC 29208 *Please consider

[R] Referencing a component of a large object (Error: slot NULL)

I am running a simulation and need to refer to a matrix of parameters from a large object. Here is a snippet of the object structure itself: Formal class 'mi' [package mi] with 3 slots ..@ call : language .local(y = y, n.chains = ..2, max.minutes = 2) ..@ data :List of 100

[R] set.cor/mat.regress

not being bound. I tried other options like square=FALSE to no avail. It seems like such a straightforward function, I'm not sure what I'm doing wrong. Any help is appreciated. Thanks Andrea -- Andrea Lamont, PhD Post-Doctoral Fellow University of South Carolina Columbia, SC 29208 *Please

[R] if, apply, ifelse

Hello: This seems like an obvious question, but I am having trouble answering it. I am new to R, so I apologize if its too simple to be posting. I have searched for solutions to no avail. I have data that I am trying to set up for further analysis (training data). What I need is 12 groups based

[R] multiple core

that there is a multicore and parallel package, but I am not understanding how to use these packages. Is there a straightforward way to tell R to use more than one processor? In my search, I found this: Sys.setenv(MC_CORES=12) but am unsure what it does... Thanks! Andrea -- Andrea Lamont, MA Clinical-Community
