[R] logical test not functioning correctly on zoo series...what the hell?

[William Dunlap]

Here is an example of the start of a self-contained way to reproduce your problem:
> library(chron) 
> library(zoo)
> rawData <- read.zoo("http://r.789695.n4.nabble.com/file/n4472408/dataout_2471_843.csv",  header = TRUE,  
+       FUN = as.chron, format = "%m/%d/%Y %H:%M", index.column = 2,
+       sep = ",", aggregate = function(x) tail(x, 1))
...

str() shows that the data is a 2-column character matrix:
> str(rawData)
'zoo' series from (02/11/12 12:45:00) to (02/22/12 08:30:00)
  Data: chr [1:1040, 1:2] "MCAS-B-2471        " "MCAS-B-2471        " "MCAS-B-2471        " ...
 - attr(*, "dimnames")=List of 2
  ..$ : chr [1:1040] "1" "2" "3" "4" ...
  ..$ : chr [1:2] "Meter.ID" "KW.ch..1..set.0."
  Index: Classes 'chron', 'dates', 'times'  atomic [1:1040] -715103 -715103 -715103 -715103 -715103 ...
  ..- attr(*, "format")= Named chr [1:2] "m/d/y" "h:m:s"
  .. ..- attr(*, "names")= chr [1:2] "dates" "times"
  ..- attr(*, "origin")= Named num [1:3] 1 1 1970
  .. ..- attr(*, "names")= chr [1:3] "month" "day" "year"

You need to figure out how to import the data as a character column and a numeric column
if you want the comparison with 0 to work.
