[R] Convert string to list?

[Ross Darnell]

Manuel

Jim's may be what you want-- a list of numerics with names P, T and Q or
a list of character strings?

> str <- "P = 0.0, T = 0.0, Q = 0.0"

> str(as.vector(unlist(strsplit(str,",")),mode="list"))
List of 3
 $ : chr "P = 0.0"
 $ : chr " T = 0.0"
 $ : chr " Q = 0.0"

Is this what you want:

> str <- "P = 0.0, T = 0.0, Q = 0.0"
> x <- eval(parse(text=paste('list(', str, ')')))
> str(x)
List of 3
 $ P: num 0
 $ T: num 0
 $ Q: num 0
