Hello, All:
I want to simulate future observations from fits to heteroscedastic
data. A simple example is as follows:
(DF3_2 <- data.frame(y=c(1:3, 10*(1:3)),
gp=factor(rep(1:2, e=3
# I want to fit 4 models
# and simulate future observations from all 4:
fit11
HI Jeff,
This might give you a start.
add_stuff<-function(x) {
x<-xinc<-NA
finished<-FALSE
while(is.na(x))
x<-as.numeric(readline("What number do you want to start? "))
while(is.na(xinc) || !finished) {
xinc<-as.numeric(readline("What number do you want to add? "))
if(is.numeric(xinc)) x

I want to apply interpolation functions from one data.table to each row
of another data.table.
interp.dt <- data.table(scen = rep(c("a", "b"), c(3, 3)), term = c(1,
20, 60, 1, 32, 72), shock = c(10, 20, 30, 9, 12, 32))
interp.fn <- function(df, x) with(df, approx(term, shock, xout = x)$y)

TL:DR there are at least three maybe four ways to address this depending on
what you plan to do.
I usually adjust PATH to add Rtools using .Rprofile. But if you do that then if
you want to use the command line to invoke R then you need to set the PATH
separately when you start the shell. For th
Stephen, I see lots of answers with packages and resources, but not
book recommendations. I have used Introduction to Data Technologies
by Paul Murrell (https://www.stat.auckland.ac.nz/~paul/ItDT/) to teach
SQL and database design and would recommend looking at it as a
possibility.

When installing packages containing code to compile, R eventually calls
