Dear List:

I have a simple two-column data set in .csv format, with the first column being the date and second column being some value. I use read.csv() to import the data as follows:

x <- read.csv("myfile.csv",header=T, dec=".", colClasses=c(Date="POSIXct"))

The structure of x is:

> str(x)

`data.frame': 2959 obs. of 2 variables:

 $ Date:'POSIXct', format: chr "1998-01-01" "1998-01-01" "1998-01-01" "1998-01-01" ...

 $ Value: num 0.07379 0.07181 0.01555 0.00630 0.00688 ...

This is not what I want. Instead, I want the structure to be the same as that of the following data set:

> str(danish)

 atomic [1:2167] 1.68 2.09 1.73 1.78 4.61 ...

"danish" is a data set that the package "evir" comes with.

Any help would be appreciated.
