I'm not familiar with whatever language that is (presumably one of the 
macro languages supported by LibreOffice?), but I would have thought 
your second condition would need to be in what appears to be the "else" 
block of the first condition, i.e.:
  testchange<-c(ifelse(testseq<=4,'x',ifelse(testseq>=5,'y',testseq)))
or maybe, if the 'c' indicates a condition:
 testchange<-c(ifelse(testseq<=4,'x',c(ifelse(testseq>=5,'y',testseq))))
or if 'c' indicates concatenation, you may not want it at all:
 testchange<-ifelse(testseq<=4,'x',ifelse(testseq>=5,'y',testseq))

Just guessing though, as I don't recognise the syntax of those lines...
