Re:
move or copy the directories mass, nnet and class to the library directory
- then execute link.html.help()
Now execute library(MASS) and data(petrol)
Should work.

nonparametric mixed model ?
Dear friends. I hope you will bear over with a lengthy question. I have a problem of 76 patients on hemodialysis measured repeatedly once a month for nine months for methylmalonic acid and vitamin B12. The vitamin had been administered previously to these patients but was curtailed in the first part and then started again. There was a very clear response in that as vitamin B12 went down

Sv: lme problem ?
Dear Douglas Bates. I just downloaded the compiled version (I'm a poor Windows devil, not yet having found the time to move to a more advanced platform...) from NT- the files are dated 30.5-1999 so they are not old - and the problem persisted....wonder what I did wrong ?

Thank you to Peter Dalgaard, who provided help for some of this solution.
It is still not ideal since the dots which are equidistant in the x-direction ideally should respect the reciprocal scale in the y-direction.
op <- par("cex"= 0.7)
x<-y<-NA
plot(x,y,xlim=c(0,10),ylim=1/c(2000,70), axes=F)

paste and path ?
Dear friends. I have trobpe with path.
Below I have tried to paste a path and file name but it will not work

Dear friends.
When using in windows version the menu function to change directory, what actions are actually performed, i.e. what commands could I write to a file to make a CD ? I couldn't find it mentioned anywhere - undoubtedly an oversigth on my part.

Dear friends.
I wanted to reproduce a sheet of paper useful for plotting the reciprocal of some biochemical variable (creatinine) over time (Bleyer Am J Kidney Dis 34:576-578,1999). Time on X axis with units years and months. On Y axis, 1/creatinine, but with the original creatinine value indicated - to make it easier for people to use it. When using the graph, the linear decrease in 1/crea over

Dear friends.
I've forgotten how to simulate data with a known correlation, e.g. only two columns. I'd be most pleased to be told.

PAR(las)
Dear friends. In the documentation for PAR it is specified that "las" allowing turning axis labels away from default=parallel to axis is not implemented. I need to make graphs with horizontal Y axis labels - how to ?
I'm using win98.
Thank you in advance.

linking object files
Dear friends. I would like to link an object file made in C. Dyn.load rather wants to link a whole library and I only wanted to link this small object file. I followed instructions given for S - by Clive Loader in his software for changepoint handling and it is his object file I made from http://cm.bell-labs.com/cm/ms/departments/sia/clive/smcp.shar
Any dirty tricks or easy oversights ?

lme problem ?
Dear friends. I tried the session below with 10 MB in both vsize and nsize but didn't get the
example work. Is this a problem in LME or in me or both or somewhere else or undefined ?

leaps and bounds
Dear friends. On the Bayesian averaging homepage http://www.research.att.com/~volinsky/bma.html I found
some S code some of which perhaps may run in R. There was a call to an algorithm possibly within S but not supported by R 64.1: "leaps and bounds". I guess it is a minimization step. Can anyone clarify the algorithm and perhaps even give a pointer to some code ?
I guess this may be

paste ?
Dear friends. I've made a very simple procedure to make Bland-Altman plots
and it works OK except for the inability to take a variate as argument in
annotation. I'm sure it is a very simple error, so if you have 5 seconds
please tell me.

array question on indexing
Dear friends,
I have struggled to do what is likely rather simple but cannot get it working.
I have a dataframe with 428 obs. of 5 variables on 26 patients. Two
variables are responses, one an index of patients (1:26), one a
period-indicator :1 :max 3, and one total time from min 1 to max 36 weeks
(max 21 entries). A complete set would be 26*21=546 long but here are only
428 entries.
Now,

data.entry
Dear friends.
Can anyone explain what is happening here ? I am told that no data entry editor is available
in this version of R ? The example is not far from that shown in help(data.entry) ?
Besides, could an empty spreadsheet entry be an option to start inputting data ?

history: recording
Hi, I'm using windows xp and R 2.8.0 - I wonder what is the command to
put in a script that has the same effect as when in a plot you choose
menu "History" and "Recording".

polr question
Dear friends.
Do Polr in Mass change the sign of the coefficients ? Example (McCullagh 1980)
options(contrasts=c("contr.treatment","contr.poly"))
library(Mass)
freq <- c(19,29,24,497,560,269)
yy <- ordered(gl(3,1,6))
z4 <- polr(yy~x,weights=freq)
> z4
Call:
polr(formula = yy ~ x, weights = freq)
Coefficients:

xaxp with dates
Dear friends.
As promised ver 1.01 solved the former problem and now dates plot OK in
windows. But.
In the following code, "cex.axis"=0.5 works OK but "xaxp"=c(14620,14680,4)
has seemingly no effect. The limits for xaxp was found from the default
plot and inspecting par(). I need to put the date marks at specific points.
Could I suppress them altogether and make a new xaxis

R2WinBUGS problem
Dear friends - I'm on winXP, R 2.71 - I have with some help dveloped
this multivariate normal model, which gives very plausible results in
WinBUGS even without any
initial values specified. However, when I then try to run the same model
via the bugs function in R2WinBUGS with inits specified as inits=NULL
the program stops in a dead end. So I have tried to make inits for the
bugs function
