I am trying to run an ancova and am having trouble setting it up properly. I have nearly 10,000 measurements of fish length, girth and stage of sexual development. I am suspicious that the stage of development is affecting the length (as they get full of eggs they get more round and are more

[R] Ghost values after subsetting

I am using subset to select the data I want to use for my analysis and find that after I subset my data frame on one column I get ghost values in the other columns. here is an example: table(data$Dags) 2008/04/12 2008/04/13 2008/04/16 2008/04/17 2008/04/19 2008/05/06 103
