I'm new to Hmisc and trying to get the following to work, but if I un-
comment the y-scale list (in order to get a log-scale for the hazard
ratio), the error bars become strangely large. The dataframe is
simply ODS output from TPHREG in SAS. Can someone point me towards
what I'm sure is a naive error? Many thanks!
tphreg1_parameterestimates1987$LCL <-
exp(tphreg1_parameterestimates1987$estimate - qnorm(.
975)*tphreg1_parameterestimates1987$stderr)
tphreg1_parameterestimates1987$UCL <-
exp(tphreg1_parameterestimates1987$estimate + qnorm(.
975)*tphreg1_parameterestimates1987$stderr)
xYplot(Cbind(exp(estimate),LCL,UCL) ~ lag|malef*ftf, groups=classval0,
as.table=T,
