[R] Accessing Results from cenmle function in NADA package

The cenmle function is used to fit two sets of censored data and test if they are significantly different. I can print out the results of the analysis on the screen but can't seem to figure out how to access these results in R and assign them to new variables, e.g., assign the slope calculated wit

Re: [R] Updating from an Old to a New version of R

On Windows, you also can use Gabor Grothendieck's copydir which is part of his utility set batchfiles available in the "Other" part of CRAN. It copies all packages which are available in a source tree but not available in a target tree from the source tree to the target tree. Then you still have to

[R] Producing a matrix of values

I all I am trying to create a matrix for a network diagram: # 1. The following produces two dataframes. The table "place" is a dataframe of all places made from "tra" a tracing table that has the source place and destination place. The table "details" is a dataframe of all source and destination
