Extract lines from text file
Hi,
I'm looking for a command to extract lines from a large text file, a
password file. A typical user has a username made from a letter
followed by their id-number.
m9718508:pw:9301:840: Lynch :/home/pgstud/m9718508:/bin/bash
So for instance if I need to extract lines where;
the 1st field, the username begins with an m
and
the 4th field, the group contains exactly 850
cat passwdfile |

Generating all possible models from full model
...nd I am always worried that I am missing models or have made a mistake somewhere. It is also difficult to alter models if I want to change a term. For example, below are the set of models I would like to run. Is there a way to specify the full model and have R generate the rest? I.e. specify
m1234567<-glm.convert(glm.nb(mantas~site*year+cosmonth+sinmonth+coslunar+sinlunar+plankton, data=mydata))
and have R run all the other models.
library(MASS)
#Intercept only
m0<-glm.convert(glm.nb(mantas~1,data=mydata))
#One term - 7 models
#Manta abundance is greater at one of the two sites...
