ParseT: Parse text string.

In google/amss: Agreggate Marketing System Simulator

Description

Shorthand for parse(text = ...), frequently used with data.table This saves us from having to redo row selection in the env argument of EvalText().

Usage

ParseT(text)

Arguments

text	string to be sent as text argument to parse.

Value

the text as an expression, result of calling parse(text = text).

Note

Including outer eval() call in the shorthand caused errors, and needs to be done separately.

Examples

dt <- data.table::as.data.table(mtcars)
colname <- "mpg"
dt[1:5, eval(amss:::ParseT(colname))]
dt[, (amss:::PasteD(colname, "plus1")) := eval(amss:::ParseT(colname)) + 1]
