Hello there, I want to create a string from strings and numbers, here is my code: str<- "name"& toString(20)
Where did you get that syntax from ? You need to use paste. > paste( "name", 20 ) [1] "name 20"
but it returns me this error: Error in toString(20) : could not find function ".jcall" what did I do wrong? I couldn't find this error anywhere...
.jcall is in rJava, but rJava never calls toString. Can you attach a bit more information as requested by the posting guide :
