Dear all,


In the end I try to run a system dynamics simulation in R using the package
deSolve.
Therefore I need an auxiliary list (auxs) the model can refer to when it the
functions need an auxiliary value.

I used a manual list:

auxs <- c( aSplitSN=0.4 , aSplitLN=0.6, aSplitSR1=0 , aSplitLR1=1, aSplitSR2=0 ,
aSplitLR2=1, aSplitSR3=0 , aSplitLR3=1, aSalesNR=0.92, aSalesRR=0.08, […])

This is vector not list.
auxs <- c( aSplitSN=0.4 , aSplitLN=0.6, aSplitSR1=0 , aSplitLR1=1, aSplitSR2=0)
is.vector(auxs)
[1] TRUE
is.list(auxs)
[1] FALSE


this way everything worked well.

Now I want to use a matrix with different values for each of the auxiliaries in
order to run different scenarios. Therefore I created a csv document wich I read
in:

csv1  <- read.csv("180713_Taguchi Robust Design Test_180709_1745.csv", sep
= ";")

list_csv <- csv1[1,]

which is probably data frame

test<-vec[1,]
is.vector(test)
[1] FALSE
is.list(test)
[1] TRUE
is.data.frame(test)
[1] TRUE



namesauxs <- names(list_csv)

auxs1 <- as.numeric(list_csv)

names(auxs1) <- namesauxs

auxs <- auxs1


Looking at the global environment section in R studio, now both are the same,
in the value section as "Numed num"

I do not know rstudio but you could check two objects by
?identical


Yet, the model will not run using these values ultimately coming from the csv.

I wonder why do you use as.numeric in the first instance. You coud use

auxs1 <- unlist(csv1[1,])
and you should get named numeric vector. Maybe there are problems when reading numbers from csv file. You could check it e.g. by

str(auxs1)


What am I doing wrong here?

It would be great if you could help.

Thanks a lot in advance

Yours

Jan
