Fit initial time with modFit and modCost
...s example it's of course trivial, it suffices
to find the first non-zero entry, but it become more challenging when
e.g. the data is noisy).
However, it seems that modFit can not do this, at least not in a
straight forward manner. Here is my minimal example:
###########
library(FME)
#function makeframe creates a vector with 10 entries, the first t0
entries are 0, the remaining entries are h. Output is a #data.frame
with "time" (1,2,...,10) and "M" (0,...,0,h,...,h)
makeframe <- function(Par){
with(as.list(c(Par)),{
t <- seq(1,10,by=1)
vec <- h*as.numeric(t>t0)

nested looping functions and dataframes
Hey All,
So, I am confused how exactly to use nesting loop functions in R to spit out
data frames. I've managed to create a working function for my data set that
generates a data frame for a given set of Year i and Location j; but how
would I do it for all Years and Locations?
Here is my working function:
test<-function(i,j){
a<-x[which(x$Year==i & x$Location==j),]

creating a data frame from a list
Dear all,
A few months ago, I asked for your help on the following problem:
I have a list with three (named) numeric vectors:
> lst = list(a=c(A=1,B=8) , b=c(A=2,B=3,C=0), c=c(B=2,D=0) )
> lst
$a
A B
1 8
$b
A B C
2 3 0
$c
B D
2 0
Now, I'd love to use this list to create the following data frame:
> dtf = data.frame(a=c(A=1,B=8,C=NA,D=NA),
