FLR

There are a few bugs in FLCohort that make it difficult to use i.e.

#1) There is no creater
flc <-FLCohort(NA,dimnames=list(age=1:10,year=1980:2000,iter=1:100))

# You can get round this by creating an FLQuant first but that is not what you need if you want to create year-class structure
# e.g. fast/slow growing cohorts
flc <-FLCohort(FLQuant(NA,dimnames=list(age=1:10,year=1980:2000,iter=1:100)))

#2) You can´t create an FLQuant from an FLCohort
flq <-FLQuant(flc)

#You can work around this by creating a data.frame first
df <-as.data.frame(flc)
df$year<-df$cohort+df$age

#3) but even though you have all the required columns in te data.frame you can´t create the FLQuant
flq <-as.FLQuant(df)

# You have to remove the redundant column, I don´t see why this be so. The redundant data should be ignored
flq <-as.FLQuant(df[,-2])

#4) There is no corresponding as.FLCohort
flc <-as.FLCohort(df[,-8])

#5) You can´t create a data.frame from an FLCohort
dfc<-data.frame(flc)


We can correct this by implementing the corresponding methods
