...t the full object name. R now seems to use that (unique) object which shares the same beginning of the called object, even though the originally called object might not even exist. This is quite awkwardly described, but perhaps you know what I'm talking about? Let's say I'm using the Mroz data supplied with the car package: require(car) data(Mroz) there is no variable called "w" in that dataframe, but calling summary(Mroz$w) #### Mroz$w does not exist does not return any error but instead gives the same result as summary(Mroz$wc) ##### exists in Mroz I find this b...

Dear All, I would like to publish a function for 'heckit' estimations together with two examples from Greene's and Wooldridge's econometric textbooks. These examples use the dataset of Mroz (1987) that is also available in John Fox' "car" package. However, not all variables that are used in my examples are available in the "car" package. Therefore, I want to put the full Mroz dataset in my package. This full dataset can be downloaded from some internet site...

...: Model not from logistic regression". I have replicated the issues below, using data and the model from John Fox's car package. Is there some editing I can do to the list from bigglm that will allow utilization in epicalc, or some other technique? Thanks in advance. library(car) data(Mroz) Mroz$in.wf <- ifelse(Mroz$lfp == 'yes', 1 ,0) mod.bigglm <- bigglm(in.wf ~ k5 + k618 + age + wc + hc + lwg + inc ,data=Mroz ,family=binomial(link='logit') ) mod.glm <- glm(in.wf ~ k5 + k618 + age + wc + hc + lwg + inc ,data=Mroz ,family=binomial(link='...

...frame with a few covariates might be a useful addition to "datasets". For example a more granular version of the "Titanic" data (in addition to the 4-way tabel ?Titanic). Or another relatively straightforward data set, popular in econometrics and social sciences is the "Mroz" data, see e.g., help("PSID1976", package = "AER"). I would be happy to help with these if such additions were considered for datasets/stats. On Sat, 15 Dec 2018, David Hugh-Jones wrote: > I would argue examples should encourage good practice.

FWIW, before all the examples are changed to data frame variants, I think there's fairly good reason to have at least _one_ example that does _not_ place variables in a data frame. The data argument in lm() is optional. And there is more than one way to manage data in a project. I personally don't much like lots of stray variables lurking about, but if those are the only variables out
