Hello,
I am wondering how to get the quotation marks into a variable expression. I
can't escape it with the backslash \ ...
Example:
I can access my data frame via
TABLE$"2011-01-02"$columnD
Now I want to do this automatically.. (with a for loop)..
Use the form
TABLE[["2011-01-02"]][["columnD"]]
and you can easily replace:
a<- TABLE
b<- " \"2011-01-02\" "
use simply
b <- "2011-01-02"
c<- "columnD"
Now forget the nonsense below and just do:
TABLE[[b]][[c]]
Uwe Ligges
acessmytable<- paste(a,b,c, sep="$")
parse(text="accessmytable")
eval(accessmytable)
It will return
[1] "TABLE$\"2011-01-02\"$close"
but I need
TABLE$"2011-01-02"$close
I highly appreciate your help!
Sincerely,
