summary of arima model in R
Hi, I want to give a summary or anova for "arima" model in R, as "summary", and "anova" for "lm". As including various intervention factors in arima(xreg = ) part, I want to assess the significancy of thse factors. I can do it using interrupted analysis of time series by linear regression, but want to see whether arima model works for the data first.

New matrix function
I think you are confusing package and function here. Plus some of the R Core packages, that you mention, contain functions that should probably be replaced by functions with better implementation from packages on CRAN.

memory footprint of readRDS()
Dear all, I tried to read in a 3.8Gb RDS file on a computer with 16Gb available memory. To my astonishment, the memory footprint of R rises quickly to over 13Gb and the attempt ends with an error that says "cannot allocate vector of size 5.8Gb". I would expect that 3 times the memory would be enough to read in that file, but apparently I was wrong. I checked the memory.limit() and that

weighted.median function from package R.basic
Dear all, I want to apply a weighted median on a huge dataset, and I remember a function from the package R.basic that could do this using an internal sorting algorithm qsort. This speeded things up quite a bit. Alas, I can't find that package anywhere anymore. There is a weighted.median function in the package limma too, but I didn't use that before. Anybody who knows what happened to

data.table not available as win binary for R 3.5 yet?
Dear all, to my astonishment data.table cannot be installed on R 3.5 Windows. When checking the package page, the Windows binary is available for download. When checking the server however, I can't seem to find data.table. Also install.packages() says the package is only available in source form and may need compilation. Compiling using Rtools 35 is no problem. Is this merely an issue of

Date class shows Inf as NA; this confuses the use of is.na()
And now I've seen I copied the wrong part of ?is.na > The default method for is.na applied to an atomic vector returns a logical vector of the same length as its argument x, containing TRUE for those elements marked NA or, for numeric or complex vectors, NaN, and FALSE otherwise. Key point being "atomic vector" here. On Sat, Jun 9, 2018 at 1:41 PM, Joris Meys <jorismeys at

cluster analysis and supervised classification: an alternative to knn1?
Hi, I have a 1.000 observations with 10 attributes (of different types: numeric, dicotomic, categorical ecc..) and a measure M. I need to cluster these observations in order to assign a new observation (with the same 10 attributes but not the measure) to a cluster. I want to calculate for the new observation a measure as the average of the meausures M of the observations in the cluster

Best practices in developing package: From a single file
Dear All: stepping in late, but @Joris, if you would like to take 'from a single file' literally, have a look at: https://github.com/bpfaff/lp4rp (lp4rp: literate programming for R packages); Cheers, Bernhard ps: incidentally, within the noweb-file roxygen is employed. -----Urspr?ngliche Nachricht----- Von: R-devel [mailto:r-devel-bounces at r-project.org] Im Auftrag von Joris

CRAN checks give errors when no tests are included
Dear all, as a follow-up to the question asked on R-package-devel (see link below): Someone sent a package to CRAN with a few problems. There's more things wrong with the submission, but one thing that really caught my eye was the following error: Warning message: running command '"C:/PROGRA~1/R/R-33~1.2/bin/x64/R" CMD BATCH --vanilla "testthat.R"

Date class shows Inf as NA; this confuses the use of is.na()
Indeed. as_date is from lubridate, but the same holds for as.Date. The output and it's interpretation should be consistent, otherwise it leads to confusion when programming. I understand that the difference exists after asking a question on Stack Overflow: https://stackoverflow.com/q/50766089/914686 This understanding is never mentioned in the documentation - that an Inf date is actually

download.file does not process gz files correctly (truncates them?)
Dear all, I've noticed by trying to download gz files from here : https://www.ncbi.nlm.nih.gov/geo/query/acc.cgi?acc=GSM907811 At the bottom one can download GSM907811.CEL.gz . If I download this manually and try oligo::read.celfiles("GSM907811.CEL.gz") everything works fine. (oligo is a bioConductor package) However, if I download using download.file("

Apparent bug in behavior of formulas with '-' operator for lm
Joris, the point is that 'z' is NOT used as a predictor in the model. Therefore it should not affect predictions. Also, I find it suspicious that the error only occurs when the response variable conitains missings and 'z' is unique (I have tested several other cases to confirm this). -Mark Op vr 16 mrt. 2018 om 13:03 schreef Joris Meys <jorismeys at gmail.com>: >

Creating S3 methods for S4 classes (coming from r-package-devel)
Dear all, I asked this question on r-package-devel but Martin Maechler pointed out this was more suited on R-devel. So here it goes: per the manual, one should create and register both the S3 and a S4 method if one needs a method for an S4 class for a function using S3 dispatching. This is cumbersome, and not very optimal. I was wondering if there's a better way to do this. Currently I

ordinal variables
Dear colleagues, I teach statistics using SPSS. I want to use R instead. I hit on one problem and I need some quick advice. When I want to work with ordinal variables, in SPSS I can compute the median or create a barchart or compute a spearman correlation with no problems. In R, if I "read" the ordinal variable as numeric, then I cannot do a barplot because I miss the category names. If
