It seems to me that there is a problem with conversion from data to
known type - the last two lines contains comments instead of data and
first column type is not recognized. You can supress all conversions,
remove problematic lines and then make conversion manually or import
only relevant lines and specify types. For example:
file<-read.csv(tmp, sep=";",
dec=",",skip=5,header=FALSE,nrows=495,colClasses=c("character","numeric","NULL","NULL"))
