Re: [R] [FORGED] Extracting specified pages from a lattice ("trellis") object.

[Duncan Mackay]

Hi Paul, Rolf

I do not know how legal this is but this works if you have spaces around the 
ultimate plot due to changes in layout
Changing the layout parameters removes the unwanted space.

ap = dotplot(variety ~ yield | year * site, data=barley,layout = c(2,6))
apm = ap[1:2,3:4]
apm$layout <- c(2,2)
apm

Hi

Does this not do what you want ... ?

allpages <- dotplot(variety ~ yield | year * site, data=barley,
 layout=c(2,2))
page2 <- allpages[1:2, 3:4]
print(page2)

I don't know if I am adding signal or noise here, but I installed R 3.5.0 yesterday and

installed, it does all the work for you.


I agree, subject to a couple of caveats.

1.  There are apparently instructions online that somehow mess up the 
installation of Rtools, putting it in a location that doesn't work 
without other changes that aren't described.  If people just run the 
installer and accept the defaults, it works.  Don't trust bloggers, 
trust CRAN.


2.  data.table fails its self-tests in 3.5.0, as shown on CRAN. 
Apparently fixes are in the works, but being able to install it doesn't 
mean it will work properly.

Dear Akhilesh,

I hope that it's clear that the Windows binary I provided for the data.table

so that it passes its own tests. You should be careful using the package in its

Dear Sir,

I am using R on Windows OS platform. I upgraded my R-system to

version

R-3.5.0. While upgrading my libraries in R as well as in RStudio, I am
stuck up in the package 'data.table', which is required by many

I tried to install 'data.table' from "USA-berkely" and "UK-bristol"  as

[R] about combining analysis results using package 'flexmix' and ' mice'

[Zhang Wilson]

Hi,

I am currently using package ‘mice’ to do multiple imputation for tourist
data here. Then the  complete datasets (e.g. m>= 100)  will be analyzed
with a finite mixture model using package ‘flexmix’. I have found that it
seems no feasible way to combine the multiple results into a final one
smoothly using just a few commands. By the way I have seen that package
like ‘semTools’ has such function to combine the ‘within variance’ and ‘
between variance’ for the estimated parameters, but it applies for SEM
models only. Do you have some recommendations about the combinations of
results after ‘mice’ and ‘ flexmix’ packages if available? Thank you very
much.


Sincerely

Wei

Yes. Using Rtools to install the package from source or installing the binary I 
provided is just a band-aid that allows packages with dependencies on 
data.table (direct or indirect) to load.

Re: [R] Package 'data.table' in version R-3.5.0 not successfully being installed

[peter dalgaard]

Hmm, looks like that thread has more noise than signal...

AFAICT, data.table currently fails selftests i 3.5.0 on all platforms on the 
CRAN builders, so RTools issues are only incidental and it would be better to 
fix data.table in the sources.

 Here is some unsolicited advice:  I would strongly recommend that you
 make it a higher priority to have backups available.  In my experience
 computer hardware is becoming quite reliable, but software isn't, and
 the person next to the keyboard isn't either.  (My last desperate need
 for a backup was due to a hardware failure 2 years ago, but it wasn't
 the manufacturer's fault:  my laptop accidentally drowned.)
 
 Backups can save you a lot of grief in the event of a mistake, or a
 software or hardware failure.  But even in the case of routine events
 like software updates that don't go as planned, they can save time.
