Hello list,
I have a function that I wrote in C to be called in R. I've done that
using symbol.C, which is the method I came across on the internet.
Now that it's supposed to be deprecated and can be removed in the
next version of R (!!), what up-to-date method that replaces symbol.C?

x is the value you asked for. I think you are confusing its printed
representation
with its value. Try cat(x) and strsplit(x, )

Hi!
distances - order(distancevector(scaled_DB, scaled_DB['query',],
d=euclid))
Just compute the distances WITHOUT ordering, here. And then
1) create a small top_five frame
top = scaled_DB[rank(distances)=5, ]
rank() is better for this than order() in case there are ties.

Hello, Im with a problem in using nonlinear quantile regression, the
function nlrq.
I want to do a quantile regression o nonlinear function in the form
a*log(x)-b, the coefficients a and b is my objective. I try to use the
command:
funx - function(x,a,b){
res - a*log(x)-b
res
}
Dat.nlrq
This isn't a nonlinear QR problem. You can write:
f - rq(y ~ log(x), data=Dat, tau=0.25)
which corresponds to the model
Q_y (.25|x) = a log(x) + b
note the sign convention on b.

Hello list members,
I'm looking for a way to force the results of a crosstabulation to be
square - that is, to include 0 values.
For example:
table(letters[1:4],letters[c(1:3,3)])
yields:
a b c
a 1 0 0
b 0 1 0
c 0 0 1
d 0 0 1
I would like to return:
a b c d
a 1 0 0 0
b 0 1

Use factors with specified levels.
lev - letters[1:4]
table(factor(letters[1:4], levels = lev),
factor(letters[c(1:3,3)], levels = lev))
a b c d
