R help - Mar 2012 - Vector errors and missing values

Hi,

I am trying to run two Non-Gaussian regressions: logistic and probit. I am
receiving two different errors when I try to run these regressions and I am
not sure what they mean or how to fix my syntax.

Here is the logistic regression error:

Error in family$linkfun(mustart) : 
  Argument mu must be a nonempty numeric vector

Here is the probit regression error:

Error in pmax(eta, -thresh) : cannot mix 0-length vectors with others

The dataset that I am using has some missing data. R puts NA values in place
of the missing values. I am not sure if this is what is causing my vector
problems or not. I have tried to use the 'data=na.omit(DataMiss)' in my
glm
as well as the command: 'na.action=na.exclude', but I am not sure if I
am
using the correct syntax because it is not working. 

Any help would be most appreciated.

Without any code and structure of your data you probably does not get much 
help. See the bottom of any email. 

PLEASE do read the posting guide 
http://www.R-project.org/posting-guide.html
and provide commented, minimal, self-contained, reproducible code.

Probably somehow your data are not as you expect. What 

str(yourdata) tells you? Is it in compliance with function you use?

Petr
