It is REALLY difficult to understand what you want to achieve.
There is no problem in your function (I do not get any error when I copy
it to R) but it is a mystery how you would like to use it, there is no
output from the function.
I am also almost sure that a or b is not defined for function
zywnoscCalosc. (Try to search nested function in help archive.
A wild guess is that
zywnosc=ifelse(is.na(sklepik),NA,sklslodycze+2)
is what you want, however without working example and/or explanation what
you REALLY want it is just a guess.

Thank you very much ;)

Your error message is because if wants a single value and you are giving
it a vector.
Typically you want to use functions all or any to correct this error
message (look them up ?all ?any) and eg if(any(is.na(...))) But in this
case to accomplish the task you're after I don't even think you want to
use an if. I am not going to give you precise code because I wasn't able
to decipher exactly what you were trying to do but something like:
b[is.na(a)] = 43
might be helpful. This line would put a 43 in b in the corresponding
entry that was na in a.
Good luck!.

but I would create sth like this:
for i in 1:length(a){
if (wsp[i] == is.na(a)) {b=43}
}
or like this
if(is.na(a)) b=3 else a
[1] 1 NA 3 3 3
but I always get an error:
the condition has length 1 and only the first element will be used
Could you help me how I may avoid this problem and use function is.na
inside
function if - else
Please

[R] function inside ifelse
Hi,
Could you tell me, if it's possible to create ifelse and put function
inside, for example:
code{
ifelse ((is.na(vek)), call_fun_1(arguments), call_fun_2(arguments))
call_fun_1 - function(arguments)
{ sth...
}
}

Re: [R] Question about rpart(sth~.,database)

My question is: What exactly mean Class~.,? It means include all remaining variables in HouseVotes84 on the rhs of the formula, i.e. as variables that should be used to predict the Class variable. Why when I use Class~., - then I get the best solution but when I use as a parameter like this: hv.tree2=rpart(V2~.,HouseVotes84) Why does this surprise you? You are now trying to predict the variable V2 (y/n) from Class and all remaining variables. I also get solution but not such good like before. They are solutions to two different problems. If you want to predict Class, then you need Class ~ ., data = HouseVotes84 or, to specify exactly which variables to use as predictors of Class, state them explicitly: Class ~ V1 + V3 + V4, data = HouseVotes84 I think you should look at the documentation that comes with R (An Introduction to R) or some of the contributed help documents on the R Website to read up on model formulae and how to represent models using this notation.

[R] data$ID - I always get a NULL
I have database write as .csv file. When I want to get sth from my database I get NULL, but I know that there is sth! For example: data$ID NULL data$kod NULL but command like below is always recognize by R data[2,3] [1] '082' In my opinion this problem is also connect with my attempt to create a tree. I always get errors. t.tree0=rpart(ID~.,t.train) Error in eval(expr, envir, enclos) : object ID not found t.tree0=rpart(kod~.,t.train) Error in eval(expr, envir, enclos) : object kod not found What I should do to create my simple trees? -- View this message in context: http://www.nabble.com/data%24ID--%3E-I-always-get-a-NULL-tp23128214p23128214.html Sent from the R help mailing list archive at Nabble.com. __ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
