Hello,

I have an R function which includes the statement LBAuo<- -9999.  Rather 
than printing out -9999 I want it to print out - infinity.
As of yet I have not been able to do that.  I am not in a graphics 
window just outputting a set of variables.  Can you help?
Thanks.

Sincerely,
Mary A. Marion

Hi Mary,

Something such as
> plot(1,1)
> title(expression(paste("LBAuo = -", infinity)))
Is this what you're after?

Best

Steve McKinney

Hi,

LBAuo <- -Inf was helpful but what I really would like to do is use the
"Greek" expression for
infinity that is the number 8 on its side.

syntax   meaning


infinity        infinity symbol
was found using ?plotmath but I don't know how to use this information.  Any
ideas?

Thank you.

Sincerely,
Mary A. Marion

Hello,

I have an R function which includes the statement LBAuo<- -9999.
Rather
than printing out -9999 I want it to print out - infinity.
As of yet I have not been able to do that.  I am not in a graphics
window just outputting a set of variables.  Can you help?
Thanks.

Sincerely,
Mary A. Marion
