Can someone please have a look at this query on stackoverflow?
Dear Olivier,
Many thanks for your reply.
Very cool.
You know what I thought ? I thought you had modified the A4 sheet size
to compute the paperheight and paperwidth ?
I wonder if that's another way of proceeding.
Best,
Ashim

SpreadLevelPlot for more than one factor
Dear All,
we need to do :
library(car) for the spreadLevelPlot function
I forgot to say that.

And indeed again (I did not understand your previous question exactly
at first), the 'hard-coded' definition of a landscape a4 sheet would
therefore be:
paperwidth=29.7cm, paperheight=21cm

SpreadLevelPlot for more than one factor
Dear All,
I want a transformation which will make the spread of the response at all
combinations
of 2 factors the same.
See for example :
boxplot(breaks ~ tension * wool, warpbreaks)
The closest I can do is :
spreadLevelPlot(breaks ~tension , warpbreaks)
spreadLevelPlot(breaks ~ wool , warpbreaks)
I want to do :
spreadLevelPlot(breaks ~tension * wool, warpbreaks)
But I get :

SpreadLevelPlot for more than one factor
Dear Ashim,
I?ll address your questions briefly but they?re really not appropriate for
this list, which is for questions about using R, not general statistical
questions.
(1) The relevant distribution is within cells of the wool x tension
cross-classification because it?s the deviations from the cell means that
are supposed to be normally distributed with equal variance. In the

Can someone please have a look at this query on stackoverflow?
Dear Ashim,
these are documented in the LaTeX 'geometry' package (see for example
on CTAN: https://ctan.org/pkg/geometry). As I added in my response on
Stackoverflow, several parts in the RMarkdown header actually concern
information that are processed by LaTeX to actually generate the PDF,
among which the 'geometry' line. For someone who is used to working with
LaTeX, it is

Understanding which
Dear All,
Here is a reprex:
> x<- 1:100
> x[-which(x>100)]
integer(0)
In words, I am finding out which indices correspond to values in x which
are greater than 100 ( there are no such items ) . Then I remove those
indices. I should get back the x that I started with since there are no
items in x which are bigger than 100 . Instead, it is returning an empty
vector.
Why is this ?

Dear All,
I had done an automatic upgrade of my Debian 10 system which had also
upgraded R.
I reinstalled the stargazer package and the error went away.

Dear Olivier,
Many thanks for your reply.
This works well for me.
How did you come up with the pagewidth / pageheight numbers? I do
understand that their ratio = 16:9,
but how did you choose these numbers?

Does replacing some values of a zoo object by NA reduce it's size ?
Dear R-helpers,
Please have a look at the following. f1 is the same as f2 except that it has
some values replaced by NA. But it's corresponding file is slightly bigger
than the file containing f2. Could someone please tell me if this is an
anomaly ?

Dear Ashim,
Try spreadLevelPlot(breaks ~ interaction(tension, wool), data=warpbreaks) .
I hope this helps,

SpreadLevelPlot for more than one factor
Dear Sir,
Many thanks for your reply.
I have a query.
I have a whole set of distributions which should be made normal /
homoscedastic. Take for instance the warpbreaks data set.
We have the following boxplots for the warpbreaks dataset:
a. boxplot(breaks ~ wool)
b. boxplot(breaks ~ tension)
c. boxplot(breaks ~ interaction(wool,tension))
d. boxplot(breaks ~ wool @ each level of tension)

Understanding which
Look at
which(x>100)
This is a zero-length vector. The negative of nothing is nothing, not a list of all possible index values.
Do you want
x[ !( x > 100 ) ]
?

Dear Ashim,
I don't think the aspectratio is appropriate in this context because
it would imply that the beamer (LaTeX) class is used but you're actually
using the article (LaTeX) class.
You may use specifications of the geometry package rather than
specifying options to the class:
e.g. replace your current header:
---

Default value of the option initial in the ses function in the forecast package.
Dear All,
I am trying to use the function ses from the forecast package.
>From its help I have :
Usage:
ses(y, h = 10, level = c(80, 95), fan = FALSE, initial = c("optimal",
"simple"), alpha = NULL, lambda = NULL, biasadj = FALSE, x = y, ...)
My query is that if I do not mention the initial value will its default
value be "optimal".
A MWE would be

Default value of the option initial in the ses function in the forecast package.
The first one, i.e. "optimal"; check help for match.arg() for the idiom.

Coercing a character zoo to a numeric
Dear R-helpers,
It seems to me that a character zoo cannot be coerced to a numeric zoo.
Below is a minimal example. Can someone tell me what I have done wrong?

> coredata(z)<-as.character(coredata(z))
