[R] How to read from a file within a gzipped file

[Rui Barradas]

Hello,

You can create a connection and read from it.

desc <- "X:/Mkt Science/Projects/ tv/202109.ext/tsa.20210901.xml.zip"
fname <- "20210901.socioDemos.a.xml"
zz <- unz(desc, fname)


Now read from zz. Example:


xml <- XML::xmlParse(zz)


Hope this helps,

Rui Barradas
