How to get multiple Correlation Coefficients
Hi
I have used a polycor package for categorical correlation coefficients.
I run the following script. But there were no results.
Could you tell me how to correct the script?
Thanks in advance,
vars <- names(sdi)
for (i in 1:length(vars)) {
for (j in 1:length(vars)) {
paste(vars[i]," and ", vars[j])
polychor(vars[i], vars[j])
# corr
}
}

how to get correct coefficients from lm model
Howdy
I apologize for duplicated posting. But I decided to correct my previous
posting.
I had the regression results using
r <- lm(Y ~ nemp + as.factor(devt), data=d).
First, there is the result of anova(r). Here I could not find regression
coefficients.
Response: Y

It is not clear about importing a plain text file, and them converting that
text file into TermDocMatrix file, etc to me.

best analysis method : for time series ans cross sectional data
Howdy
What I 'd like to analyze with a large data on building permits is to find
time series effect of urban policy on buildings as well as
cross-sectional effects in any. In 1990 the specialZone urban policy
was introduced. I guess that the effects of this specialZone policy
would be different from countys. There are counties that do not
welcome this specialZone forced to design it.

How to avoid automatic coercion to factor?
I have a function that manipulates a list of numeric and character
components of equal length and wants to return a data.frame.
EG,
f<-function() {
a<-list(Int1=1:5,Char1=letters[1:5],Char2=letters[6:10])
b<-data.frame(a)
}
How can I get the columns Char1, Char2, (...CharN) returned coerced to
character and not factor?
It appears that I could coerce individual columns by

Apropos sprintf behavior
If changes to sprintf behavior are being considered, would it
be possible to allow some of the other K&R conversion
specifiers?
xX - for integer to hex conversion, and
c - for ascii value to character conversion
would all be useful for me.
Thanks, Steve Dutky

R (unix) command line editing for native speakers of vi
As an inveterate user of vi, I was pleased to stumble on how
to use it for editing R commands.
When an interactive R session is launched under unix, the
command line editor most likely defaults to emacs. Typing
<esc>,<ctrl>+j will switch this to vi editing mode (see below
for possible exceptions).
excerpted from readline(3) manpage:

standard naming for components of R data structures
I need to write some documentation:
I'm looking for a standard, consistent way of referring to the components
and attributes of R data structures. Googling and Stackoverflow yield a
variety of github sites that do not seem to be particularly authoritative.
I was hoping to find a BNF/ABNF grammar for R.
I've looked at the output of bison -v ./R-3.6.2/src/main/gram.y but it does
