[R] cv.binary problem
HI,I am analyzing a risk model for type 2 diabetes using a logistic regression. In the final model I have only 6 predictors. The regression gives correct output (fullmod is the fitted model). Now I try to do cross validation using cv.binary. Any help in resolving this problem will be appreciated. > cv.binary(fullmod) Error in sample.int(x, size, replace, prob) : invalid 'size' argument Regards,Amit [[alternative HTML version deleted]] __ R-help@r-project.org mailing list -- To UNSUBSCRIBE and more, see https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
[R] cv.glm problem
HI,I am analyzing a risk model for type 2 diabetes using a logistic regression.
In the final model I have only 6 predictors. The regression gives correct
output (fullmod is the fitted model). Now I have a subset of dataset (mydata1)
with 7 variables (1 response(0/1) + 6 predictors) and try to do cross
validation using cv.glm. The dataset mydata1 has 1410 rows and no NA entry.
This is the problem I run into (It does not matter what K I choose). Any help
in this matter will be appreciated.
> cv.glm(mydata1,fullmod,K=6)
Error in if ((K > n) || (K <= 1)) stop("'K' outside allowable range") :
missing value where TRUE/FALSE needed
Regards,Amit

problems. For me I had to essentially resource bicolite everytime as below.
Also, try to put quotations around your package names after the bioclite
command, see it that works Sep 29 at 3:08 PM Hi David,This is the
problem now with ReadAffy(). I have all files in myRfolder. Let me know what
