The problem is that since there is a space between the date and time
and you are also using a space to separate fields the file has become
inconsistent.
It would be better to write it out as a csv file so that the date and
time remain as a single field.
If its too late for that then you can still recover it but its a bit
more work. First get the column names and then read everything but
the header adding the column names yourself like this:
library(zoo)
File <- "test2.txt"
cn <- c("Date", read.table(File, nrow = 1, as.is = TRUE))
z <- read.zoo(File, header = FALSE, skip = 1, index = 1:2, tz = "",
col.names = cn)
