...from x1 to x7 equals to 40 --> 0, else --> 1 I was trying to do something like: count40aux<-ifelse(test[,2:8]==40,0,1) count40aux It doesn't work as i expected... Can anyone help me please?

I suspect that the issue is addressed (obliquely) in the examples, which shows that variables with spaces in them (or otherwise 'non-syntactic', i.e. not satisfying the constraints of legal R symbols) can be handled by protecting them with backticks (``) ## using non-syntactic names: reformulate(c("`P/E`", "`% Growth`"), response = as.name("+-")) It

Hi, Sorry for writing this late, I was very busy. I started this discussion here. I wish I could write to bugs.r-project.org, but I don't have an account and I will write here instead. Meanwhile, I solved my problem with a simpler fix (please see attached file)/. / This requires that term labels are not "ticked". I think this is better, since it is easier to have column names

Your file didn't make it through the mailing list (which is quite restrictive about which types/extensions it will take). I appreciate your enthusiasm and persistence for this issue, but I suspect you may have trouble convincing R-core to adopt your changes -- they are "better", "easier", "more intuitive" for you ... but how sure are you they are completely

Well, first I can't sign in bugzilla myself, that is why I wrote here first. Also, I don't know if I have the time at the moment to provide tests, multiple examples or more. If that is not ok or welcomed, that is fine, I can come back, whenever I have more time to properly report the bug. I didn't find the existing bug report, sorry for that. Yes, it is related. My problem was

...to me that they are doing a great job. I don't mind also someone rejecting this tiny fix I have found, which works for me now. I can only thank for their time spent considering it. Actually, I had in mind a more complex but cleaner solution with recursive functions to implement any kind of reformulation (not only with "+"). But I simple lack the big picture on R expressions, I need to read more. Maybe I will come back with that in the future.

Hi, I have found a bug in reformulate function and have a solution for it. I was wondering, where I can submit it? Best, Saren -- Saren Tasciyan /PhD Student / Sixt Group/ Institute of Science and Technology Austria Am Campus 1 3400 Klosterneuburg, Austria

The main thing is to post the "small reproducible example". My (rather long term experience) can be written if (exists("reproducible example") ) { DeveloperFixHappens() } else { NULL } JN On 2019-03-29 11:38 a.m., Saren Tasciyan wrote: > Well, first I can't sign in bugzilla myself, that is why I wrote here first.

First I wanted to thank both Marc Schwartz Greg Snow and for their reply. Then I needed to add a level of complexity to the problem. I would be able to create the biggest possible matrix. In other way does it exist a method to ask smthing like the following : max number of rows for a matrix if column=x?

Martin, ? There are a couple of issues with [.terms that have bitten my survival code.? At the useR conference I promised you a detailed (readable) explanation, and have been lax in getting it to you. The error was first pointed out in a bugzilla note from 2016, by the way.? The current survival code works around these. Consider the following formula: <<testform>>=

Hey! Our flac's official website is looking so old, isn't it? Let's reformulate it. I wanna do this, anyone else?

Has anyone had success using Sun ONE as an LDAP (authentication) back-end to Samba (preferably 4.0, but 3.3 would be fine)? I've found people who've tried and given up. Sun itself hasn't provided answers, but I haven't given up on them; I'll keep reformulating my questions, and asking again. One speculation on my part is that, if I can just figure out where in Sun ONE the

Dear all, As our previous email did not get any response, we try again with a reformulated question! We are trying to do something which needs an efficient loop over a huge array, possibly functions such as apply and related (tapply, lapply...?), but can't really understand syntax and examples in practice...i.e. cant' make it work. to be more specific: we are trying to apply a mask
