I am trying to load a csv file in my R script.Execute R script is the only operator in the program which is connected to the output.(I have printed the xml code below). It gives me an error mentioning
InOrder to import an R data frame as example set the data frame must provide attribute names. The simple file I am trying to load does have the header for the data though..So I am confused..Please help..
Thanks
