Plans to improve reference classes?
Could of requests:
1) Is there any example or writeup on the difficulties of extending
reference classes across packages? Just so I can fully understand the
issues.
2) In what sorts of situations does the performance of reference
classes cause problems? Sure, it's an order of magnitude slower than
constructing a simple environment, but those timings are in
microseconds, so one would need a

Testing for Inequality à la "select case"
...00
Once the interval is determined, the values in x are multiplied by the
percentages applying to the range in the 3rd column.
If the result is less than the fourth column, then the latter is used.
For values of x falling in the last interval, 250,000 must be used.
My best attempt at it in R:
MyRange <- function(x){
range_aux = ifelse(x<=20000, 1,
ifelse(x<=100000, 2,
ifelse(x<=250000, 3,
ifelse(x<=700000, 4,
ifelse(x<=1000000, 5,6)))))
percent = c(0.65, 0.4, 0.3, 0.25, 0.2, 0)
minimum = c(0, 14000, 40000, 7...

Here's a simple example:
library(scales)
library(methods)
MyRange <- setRefClass("MyRange", contains = "DiscreteRange")
a_range <- MyRange()
a_range$train(1:10)
# Error in a_range$train(1:10) : could not find function "train_discrete"
where train_discrete() is an non-exported function of the scales

radarchart axis scaling
Hello
I created a radar chart using the function of ?radarchart? from the
?fmsb? package in R software.
The matrix I am using is as follows:
x<-c(c(rep(4.5,7),c(rep(0,7)), 3.34, 3.28, 1.37, 1.12, 3.52, 4.07, 3.66));
a<-matrix(x,nrow=3, ncol=7,byrow=T)
I would like to show the range of c(0,5) on the axis instead of
c(0,100) or c(0,1).
I really appreciate it if any body can guide me.

difficult "for"
Hi,
My english isn't brilliant and my problem is very difficult to describe but
I try ;)
My first question is: May I write loop "for" like this or similar - for (i
in sth : sth[length(sth)], k in sth_else : length(sth_else) ) - I'd like
to have two independent conditions in the same loop "for".
My secound question depend on program below. I'd like to write every
