drop observations
Hi,
I want to drop observations with value 0 from my data.frame "dta" for each
of the two variables "c01" and "ctotale". How can I do that?
Thanks

Using Function
...desc(Idade)
M?dia Desvio CV
Idade 44.04961 16.9388 38.4539
How do you get the variable name is placed as the first
element?
My objective is get something like:
rbind(
desc(Altura),
desc(Idade),
desc(IMC),
desc(FC),
desc(CIRCABD),
desc(GLICOSE),
desc(UREIA),
desc(CREATINA),
desc(CTOTAL),
desc(CHDL),
desc(CLDL),
desc(CVLDL),
desc(TRIG),
desc(URICO),
desc(SAQRS),
desc(SOKOLOW_LYON),
desc(CORNELL),
desc(QRS_dur),
desc(Interv_QT)
)
Thanks a lot,

Package to make stepwise model selection using F or Chisq test
...hoSer
+ :
objeto "OPTIONS" n?o encontrado
Looking for OPTIONS in the code I found that this need a P.limit in an OPTIONS
object. I make it.
> OPTIONS <- NULL
> OPTIONS$P.limit <- 0.05
> m.pres.step <-
grasp.step.anova(m.pres,scope=list(upper=~(ProfSer+NgalhoSer+CTOTAL+DensRamos+Htotal+CAP)^3,lower=~1),trace=1,direction="both")

# grasp.step.anova is a modified version of step.gam of Splus using ANOVA
based on Chi or F tests instead
