Hi Kai,
How about setting:
germlinepatients$DisclosureStatus <- NA
then having your three conditional statements as indices:
germlinepatients$DisclosureStatus[germlinepatients$gl_resultsdisclosed
== 1] <-"DISCLOSED"
germlinepatients$DisclosureStatus[germlinepatients$
gl_resultsdisclosed == 0]
Hello List,
I wrote the script below to assign value to a new field DisclosureStatus.
my goal is if gl_resultsdisclosed=1 then DisclosureStatus=DISCLOSED
else if gl_resultsdisclosed=0 then DisclosureStatus= ATTEMPTED
else if gl_resultsdisclosed is missing and gl_discloseattempt1 is not missing

The data import/export manual can elaborate on a lot of these; this is
all straightforward, although many people would prefer to use a
relational database for some of the things you mentioned. I'm not
aware of a goto command in R, though (although I could be wrong).

Dear R-listers,
I am a relatively inexperienced R-user currently migrating from Stata. I
am deeply frustrated by this data manipulation question: I know how I
could do it in Stata, but I cannot make it work in R.
I have a data frame of hospitalization data where each row represents an
admission.
How about:
id - c(rep(a,4),rep(b,2), rep(c,5), rep(d,1))
start - c(c(0,6,17,20),c(0,1),c(0,5,10,11,50),c(0))
stop - c(c(6,12,20,30),c(1,10),c(3,10,11,30,55),c(6))
data - data.frame(id,start,stop)
f - function(data){
m - match(data$start,data$stop) + 1
if (length(m)==1
