R2OpenBUGS quesion
...anybody help me figure out why I get the Error message below while I

message. My R version is 2.15.1 in win7 and 2.15.0 in Ubuntu. Many thanks !
Best,
Yilong

transfer string to expression
Dear all:
when I use parse() there is some problems. Below is an example:
b0<-1
b1<-1
x<-1
str2expr<-function(x){eval(parse(text=x))}
test1<-"b0+b1*sqrt(x)"
test2<-"b0+b1"
str2expr(test1)
str2expr(test2)
it can work well for test2 but not for test1.
Could you tell me how to fix this problem or is there other more stable
method to transfer an string to
