Hi,
When I call the *switch* function first time, it works. but when I call it
at the second time, it does nothing. The version I use is R version 2.9.0
Under development (unstable) (2009-02-21 r47969)
here is the output:
> organism="human"
> species <- switch(organism,
human <- "Hs",
fly <- "Dm",
mouse <- "Mm",
rat <- "Rn",
yeast <- "Sc"
)
species <- switch(organism,
+ human <- "Hs",
+ fly <- "Dm",
+ mouse <- "Mm",
+ rat <- "Rn",
+ yeast <- "Sc"
+ )
> species
[1] "Hs"
> organism="yeast"
> species <- switch(organism,
human <- "Hs",
fly <- "Dm",
mouse <- "Mm",
rat <- "Rn",
yeast <- "Sc"
)
species <- switch(organism,
+ human <- "Hs",
+ fly <- "Dm",
+ mouse <- "Mm",
+ rat <- "Rn",
+ yeast <- "Sc"
+ )
> species
[1] "Hs"
when I change *organism* to "yeast", and call *switch* function again,
*species* suppose to be changed to "Sc", but it remain it's original value.
