[R] unz()

[Marsland, John]

I am having problems getting the unz() function to work as a connection to
start reading a file...

z <- unz("c:/temp/stoxx.zip", "close_tmi_components.txt", "r")
readLines(z,2)

yields the following problems:

> z <- unz("c:/temp/stoxx.zip", "close_tmi_components.txt", "r")
Error in unz("c:/temp/stoxx.zip", "close_tmi_components.txt", "r") : 
        unable to open connection
In addition: Warning message: 
cannot locate file `close_tmi_components.txt' in zip file
`c:/temp/stoxx.zip' 
> readLines(z,2)
Error in readLines(z, 2) : cannot open the connection
In addition: Warning message: 
cannot locate file `close_tmi_components.txt' in zip file
`c:/temp/stoxx.zip' 

can anybody offer any advice?

Regards,

John Marsland
