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
This is probably far more discussion than the question warranted, but...

aware of a "goto" command in R, though (although I could be wrong).

Can R support data manipulation programming that is available in the SAS
datastep? Specifically, can R support the following:
-Â Â Â Â Â Â Â Â Â Read multiple dataset one record at a time and compare
values from each; then base on if-then logic write to multiple output files
-Â Â Â Â Â Â Â Â Â
dles some special cases outside my small example dataset.
Thank you again!
Peter.

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.

Dear R users,
I am a new user (probably obvious by my question) and
have really learned a lot from reading this list.
Thank you all very much. My main struggles with R are
with data manipulation.
So here is my question...
I have data that is organized as below, this is a
short example.
value
Try this:
transform(d, z = y[match(x, id)])

Hi all,
Suppose I have the following data.frame, with an id column and two
variables columns :
idX Y
0001 NA 21
0002 NA 13
0003 000145
0004 NA 71
0005 000320
What I would like to do is to create a new variable Z whose values are
the Y
