[R] Could not read time series data using read.zoo()

[Gabor Grothendieck]

The header has white space in it so skip over it, use header = FALSE
and specify the
column headers yourself.  Also use fill=TRUE since the first row does
not have 3 entries.

   # generate test file
  cat("Date Adj Close lret
  02-01-1997 737.01
  03-01-1997 748.03 1.48416235
  06-01-1997 747.65 -0.050813009
  07-01-1997 753.23 0.743567202
  08-01-1997 748.41 -0.64196699
  09-01-1997 754.85 0.856809786
  10-01-1997 759.5 0.614126802", file = "1.csv")

  # test
  library(zoo)
  read.zoo("1.csv", skip = 1, header = FALSE, format = "%m-%d-%Y", fill = TRUE,
     col.names = c(NA, "Adj_Close", "Close"))
