Can plot(augPred()) be used with objects that are not groupedData?
Dear Friends,
Is there a workaround to this problem or must the object plotted by
plot(augPred(object, ...)) be a grouped object?

Observed responses in 'augPred' data frame - Wrong order ?
Dea-R community.
I'd like to draw your attention to an issue I have recently
encountered while doing my current data analysis.
I've got an unexpected (to me) result from the command:
> augPred(lmList(my.object)),
'my.object' being a grouped data frame of class:
> class(my.object)
[1] "nfnGroupedData" "nfGroupedData" "groupedData"

panel ordering in nlme and augPred plots
Hi,
I'm new at this, I'm very confused, and I think I'm missing something
important here. In our pet example we have this:
> fm <- lme(Orthodont)
> plot(Orthodont)
> plot(augPred(fm, level = 0:1))
which gives us a trellis plot with the females above the males,
starting with "F03", "F04", "F11", "F06", etc. I thought the point of

abline and plot(augPred) help
Dear all
as I did not get any response on my post about abline and
plot(augPred)) I try again. I hope I do not break some posting guide
rules. I would try to contact package maintainer directly but there
is stated to be R-core people, so I feel R-help list shall be OK.
I need to draw straight lines through augPred plotted panels
(vertical or horizontal) at specified point. I know I shall

Weird problem / bug with augPred() from nlme
Posted this to r-sig-mixed-models (https://stat.ethz.ch/pipermail/r-sig-mixed-models/2019q1/027620.html) but this might rather need to go to r-devel anyway, so reposting here:
I came across a weird problem / bug with augPred() from nlme (nlme_3.1-137). Here is a reproducible example to illustrate the issue (tested on R 3.5.2 and R-devel 2019-03-03 r76192):

nlme: augPred.lme for factor covariates
Hi everybody,
as you may be aware the function augPred.lme does not work as soon as
the covariate is a factor. The problem lies in the line
newprimary <- seq(from = minimum, to = maximum, length.out = length.out)
which does not make sense for factors. I think augPred.lme can be useful
for models with a factor covariate as well. Thus, I propose to change
the code to:
augPred.lme <-

Fix for augPred/gsummary problem (nlme library)
Dear R-users,
I am a newbie to this site and a relative new-comer to S/R, so please tread lightly, for you tread...
There have been several posting relating to problems with augPred() from the nlme library. Here is a "fix" for one of these problems which may lie at the root of others.
In my case the problem with augPred() lay in gsummary(), which augPred() uses, causing it to fail.

augPred with lme(...,subset=...)
Hello,
Is there a way to get augPred to work with lme if a subset statement is
used? For example, if I modify the example from ?augPred.lme to include
a subset statement, I get the following error:
fm1 <- lme(Orthodont, random = ~1, subset=distance>19)
augPred(fm1, length.out = 2, level = c(0,1))

Error using augPred with nlme grouped data
Hello all,
I am having a problem using augPred after I have created an nlme object. My
data is 3933 rows long with no NA's, and is grouped with this function:
vanfem<-groupedData(mass~age.years|name, data=av.mex, labels=list(x="Age",
y="Mass"), units=list(x="(years)", y="(kg)"))
Under the grouping factor "name", this is a character

plot.augPred sorted and labelled according second factor
Hi
using this code example:
library(nlme)
fm1 <- lme(Orthodont, random = ~1)
plot(augPred(fm1))
is there any way to have the plots in each cell labelled and ordered
according to Orthodont$Sex? I.e. in addition to the bar with the label for
Orthodont$Subject there is another bar labelling the Sex of the subject?
thanks a lot

I encountered strange behaviour of augPred with virtually the same data

panel ordering in nlme and augPred plots
Dear all
I am trying nlme together with Pinheiro/Bates book. I constructed
grouped data object with suitable plotting layout (according to
some common factor, panels from bottom to top are in increasing
order).
When I do nlme(... some stuff...) I get fitted object which I can plot
with
plot(augPred(fit.nlme6, level=0:1))
but it results in completely different ordering. Is there any way

strange nlme augpred behaviour
Hi
Well, yes I tried it about two weeks ago but my post did not get through as it still awaits moderator approval. I could check which column is offending but actually it is only minor nuisance, I can live with selection of columns before fitting a model. What seems to me strange is that both full dataset and only selected colums gave me identical fit results but only one works within augPred.

Problem with pairs() in nlme
Dear r-helpers,
After successfully running
require(nlme)
vfr.lmL <- lmList(
estimate ~ (slant + respType + visField + hand)^2 | subject, vfr
)
pairs(vfr.lmL, id = 0.01, adj = -0.5) # Pinheiro & Bates (p. 141)
produces the following error:
Error in sprintf(gettext(fmt, domain = domain), ...) :
object "form" not found
Any guesses as to what I may have done wrong?

augPred plot in nlme library
All,
I'm trying to create an augPred plot in the nlme library, similar to the
plot on
p.43 of Pinheiro & Bates (Mixed Effects Models in S and S-Plus) for
their Pixel data.
My data structure is the same as the example but I still get the error
msg below.

augPred in lmer
I read the posts about augPred with lme, but does anyone know if there is a correlate for augPred for lmer? Specifically, I want to be able to use it to plot projections for all groups in an lmer class object using plot(augPred(lmer.object)).
Thanks,
Kyle

plotting all subgroups with augPred
All,
I have a question RE plotting the prediction lines of a random effects
model via augPred. I'll illustrate via the Pixel dataset within the
nlme package:
library(nlme)
attach(Pixel)
fm1Pixel = lme(pixel ~ day + I(day^2), data = Pixel, random = list(Dog =
~ 1))
plot(augPred(fm1Pixel)) ### 10 fitted lines since there are 10 dogs
fm2Pixel = update(fm1Pixel, . ~ . + Side)
