Sorry, I'm using R 2.8.1 on Microsoft Windows XP professional 2002 Service Pack
2.
The error I get is
Error in write.table(x, file, nrow(x), p, rnames, sep, eol,
na, dec, as.integer(quote), :
'list' type not implemented in 'EncodeElement'
The problem is that I can' t manage to save the dataframe...
With other dataframe I usually have no problems!!!
What does sapply(carichi.annui, class) tell you?
It would be better to use
carichi.annui <-
data.frame(anno,loadPTG,loadPO4,loadNT,loadNH4,loadNO3,loadBOD5,loadSiO2)
as you don't need an intermediate matrix.
Hello,
I tried to turn lists into vectors and then bind them
together in order to create a dataframe but if, after this, I
try to use the function write.table I get the following error message:
Error in write.table(x, file, nrow(x), p, rnames, sep, eol,
na, dec, as.integer(quote), :
'list' type not implemented in 'EncodeElement'
Here is what I've done:
as.vector(c(unique(portate$Anno)))->anno
as.vector(loadListPO4)->loadPO4
as.vector(loadListPTG)->loadPTG
as.vector(loadListNT)->loadNT
as.vector(loadListNH4)->loadNH4
as.vector(loadListNO3)->loadNO3
as.vector(loadListBOD5)->loadBOD5
as.vector(loadListSiO2)->loadSiO2
cbind(anno,loadPTG,loadPO4,loadNT,loadNH4,loadNO3,loadBOD5,loa
dSiO2)->carichi
as.data.frame(carichi)->carichi.annui
#if I type
carichi.annui
#I get
anno loadPTG loadPO4 loadNT loadNH4 loadNO3 loadBOD5 loadSiO2

#which looks lika a data frame
#And if I type
is.data.frame(carichi.annui)
# I get this:
[1] TRUE
#but if I try
write.table(carichi.annui, "carichi.annui.lav")
#It doesn't work?!?!?!
Does someone have an explanation?
Thanks a lot for any help!!
Laura
Laura,
What do you mean by "It doesn't work"? Do you get error messages? Or, do
you just not get what you want? And if so, what is that you want?
