Hi, I might have misunderstood your point, but why should a Date object store a timezone, since timezone is an attribute of time, not date? Your tz-examples force R to present a timezone, resulting - this is my assumption - to default (=UTC) as there is no other information available. Best, Ki

RStudio is **not** R. In particular, the so-called TidyVerse consists of all *non*-standard contributed packages, about which the PG says: "For questions about functions in standard packages distributed with R (see the FAQ Add-on packages in R), ask questions on R-help. [The link is: https://cran.

Re: [R] Question about .Rhistory in Windows

Hallo I increased number of lines which .Rhistory stores before the lines start to be overwritten. You can do this by changing number in Sys.setenv(R_HISTSIZE = 2000) in Rprofile.site located in etc folder of your installation. And from time to time I rename Rhistory to something like "210621.r"

Re: [R] question about the difference of AIC()

In the first model, I believe you estimate two parameters: the mean and the variance: > fm <- lm(y ~ 1) > 2*2 - 2 * logLik(fm) 'log Lik.' 40.49275 (df=2) > AIC(fm) [1] 40.49275 A zero mean model: fm0 <- lm(y ~ -1) > 2*1 - 2 * logLik(fm0) 'log Lik.' 39.00611 (df=1) > AIC(fm0) [1] 39.00611 Regard

Re: [R] Question about using R sample datasets

You have already been reminded that none of us are lawyers. There is license text associated with every package and base R, and it is not necessarily the same for all parts of R, so there is no way for us to answer your question in its vague form and no way for you to rely our opinions even if y

Re: [R] Question about using R sample datasets

Thanks for the advice. What about R code? Is that free to share? I would use my own dataset or made up dataset, so I am only now interested what about R code, can I screenshot it and then explain what is on the photo? Maja ned, 2. svi 2021. u 01:17 David Winsemius napisao je: > Any answer you

Re: [R] Question about using R sample datasets

Again, the terms of the license govern the legalities. I don’t think you would need any further efforts at licensing your commentary. Screenshots or text copies would both be just copies and the appropriate citations would probably be all that were needed. I do not think your commentary or expla

Re: [R] Question

Hi Myungjin, The funnel plot is no more than the precision of the estimates of related studies plotted against the estimates. That is, if your measure of precision is the sample size (SS) and the estimate is named E, plot(E,SS) Look at the metafor package for good funnel plot functions. Egger's t

Any answer you get here will will have all the authority of "some guy on the Internet", but my reading of the licenses is that as long as you give proper credit that you can use any material in teaching or commercial purposes AND derivative works are likewise copy-able on an open source (FOSS) b

Re: [R] Question about dotwhisker

Sorry, forgot to link the actual vignette: https://cran.r-project.org/web/packages/dotwhisker/vignettes/dotwhisker-vignette.html In fact the vignette states: dwplot(m1_df) #same as dwplot(m1) where m1_df is m1_df <- tidy(m1) They are not the same in either the vignette itself or on my computer.

Re: [R] Question about the package "MatchIt"

Maria Cristina, The MatchIt homepage at https://gking.harvard.edu/matchit has a link to a mailing list specific to the package and it has searchable archives. You will probably have better luck there than a general R programming list. Though a quick perusal of the user guide at that site makes me
