I want to create a data.frame of time and date for a year. I started with the idea of simply producing two vectors (time and date) The first part ( time) is easy. rep(1:24, 365) But how do I get a series of 24 dates for O1 January 2005 and repeat this to 31 December 2005. It should be easy but I don't see it. Thanks

...regate(test1,list(test2),sum) Error in data.frame(w, lapply(y, unlist, use.names = FALSE)) : arguments imply differing number of rows: 26, 0 I thought this would give me a list containing the number of ones that "belong" to each letter. What am I doing wrong? Thanks in advance, Gustaf -- email:gustaf.rydevik at gmail.com tel: +46(0)703051451 address: Kantorsgatan 50:190 75424 Uppsala Sweden

Dear list, I would like to export a matrix to a TXT-File by using write.csv (not necessarily). Is there a way to add a header (with additional informations concerning the project) spanning multiple lines to this file before the actual data are listed up? Should look like this: date: filename: number of permutations: ------------ data (as a matrix) Any suggestions? Thnx in advance.

...() and gets way to big if I use exp(). To be honest, I get the feeling that Im on the wrong track here. Basically, I want to know how SE is calculated in effect() (all I know is that the reported standard errors are for the fitted values) and if anyone knows what is going on here.

Yes, good point. I added the checking of prev_mode for Silk DTX to avoid using stale data from the Silk state. The PR is updated, and I'm attaching an updated patch. /Gustaf On Tue, 9 Apr 2019 at 12:42, Mark Harris <mark.hsj at gmail.com> wrote: > On 2019-04-08 4:55, Gustaf Ullberg wrote: > > Thank you Mark. > > > > I agree and have now updated the pull request with a new commit, > > addressing your comments. > > Please take a l...

...(mainly because R is slow and too good at graphics, encouraging data snooping). See http://fluff.info/blog/arch/00000041.htm While I don't agree (granted, I can't really write C), it was interesting to read something from a very different perspective than I'm used to.

...to the figure. embedFonts() works for this, but the result is that text becomes low-res bitmaps, and I don't know how to solve this. So basically my question is: How should I go about generating graphics that will look as nice as possible given the above constraints?

...g average on an irregular time series, or use the rollapply function in zoo? I have a set of dates where I want to check if there has been an event 14 days prior to each time point in order to mark these timepoints for removal, and can't figure out a good way to do it.

...ems to use some other coordinate system. What kind of call do I use to make abline use the graph's coordinates? Additionally, it would be nice to have standard xy-axis, and to have the line stop at the x-axis, so if anyone could tell me how to do that, I'd be grateful. Thanks in advance, Gustaf PS: a minor question: Why do I have to call plot.new() for abline to work? -- email:gustaf.rydevik at gmail.com tel: +46(0)703051451 address: Kantorsgatan 50:190 75424 Uppsala Sweden

I thought the ANOVA table would give me a quite similar result because I only have two levels (of the infl.treat factor) and no interactions in the model. ## I'm afraid I have missed something trivial though so please, be gentle ;) Cheers, Gustaf Granath -- Gustaf Granath (PhD student) Dept of Plant Ecology Evolutionary Biology Centre (EBC) Uppsala University
