Dear R-helpers,
I am trying to generalize my function for recording measurement times from
file times "mtime"--my intervals are minutes to hours over the course of
several days. I want to use hours as my units, and I have had trouble
dealing with time units in a general way. I have a simple solution for the
dealing with regular intervals, but I have not been able to handle irregular
intervals. I tried using the zoo package, and had similar problems with the
conversion of time units.
Code and sample data is below--
for your info--after this, I am feeding the times and measurements to nls.
Thanks in advance,
-- Warren
#Here is the failed code:
myfilenames<-row.names(myfileinfo)
fileno<-length(myfilenames)
filetimes<-numeric()
for (i in 2:fileno){rel.read.time<-myfileinfo$mtime[i]-myfileinfo$mtime[1]
rel.read.time<-(as.numeric(rel.read.time))
##this next part is problematic
##i would love to say > time.in.hours<-as.hours
(myfileinfo$mtime[i]-myfileinfo$mtime[1])
ifelse(rel.read.time >=5, hour.read.time<-(rel.read.time /60),
hour.read.time<-rel.read.time)
filetimes<-c(filetimes,rel.read.time)}
#For regular intervals of readings, the code below generates measurement
times from the first interval:
myfilenames<-row.names(myfileinfo)
fileno<-length(myfilenames)
intervalue<- myfileinfo$mtime[2] - myfileinfo$mtime[1]
unitless.interval<-(as.numeric(intervalue))
ifelse(unitless.interval>=5, hour.interval<-(unitless.interval/60),
hour.interval<-unitless.interval)
hours<-0
for (i in 1:(fileno-1)){hours<-c(hours,(i*hour.interval))}
myfileinfo <-
