What is zoo? I cannot find anything about zoo int he documentation.
I did try as.ts() see below.
Thank you,

have you tried using zoo and then using the function as.ts()

Converting dates is getting stranger still. I am coercing a data frame
into a ts as follows:
tst1<-as.POSIXct("1/21/09 5:01",format="%m/%d/%y %H:%M")
tst2<-as.POSIXct("1/28/09 3:40",format="%m/%d/%y %H:%M")
tsdat<-as.ts(dat,start=tst1,end=tst2,frequency=1)
This generates a ts object. But strange
Try varying the arguments to this to accommodate
the precise format of your data. See the three zoo
vignettes, ?read.zoo and R News 4/1 for dates
and times.

I read records using scan:
dat<-data.frame(scan(file="KDA.csv",what=list(t="%m/%d/%y
%H:%M",f=0,p=0,d=0,o=0,s=0,a=0,l=0,c=0),skip=2,sep=",",nmax=np,flush=TRUE,na.strings=c("I/OTimeout","ArcOff-line")))
which results in:

t fp d o sa l c
