Dear R Friends,
I'm a medical doctor with some knowledge about statistic and programming.
I want to analysis and compare data of different countries with survival or
popEpi tools in R.
I couldn't able to make tables with one row for every people of countries
without illness. I can made a data table look like as:
time
country at.risk from0to1 sk zf from0to0
1 AFG 40363639 1 K F 0
I try to prepare for analysis with survtab_ag function of Epi package. When
I run
st <- survtab_ag(time ~ cuntry, data = xxxx, surv.type =
"surv.obs",surv.breaks=list(xxxx$time),
+ surv.method = "lifetable",
+ d = "from0to1")
I see just the error message:
Error in sort.int(x, na.last = na.last, decreasing = decreasing, ...) :
'x' must be atomic
Can any body help me for preparing this kind tabulated data without surv()
to other survival functions?
Best regards from Turkey
