Hello again,
My apologies for the delayed response... computer troubles. In reference to
Ms. Goslee's and Mr. Barry's query, the following is the error code
received after I inputted my R command
the_data<-read.csv(file="GBM_clinical_drug.csv",header=TRUE,sep",")
Error: unexpected string constant in
"the_data<-read.csv(file="GBM_clinical_drug.csv",header=TRUE,sep",""
Given this, should I proceed with implementing the path<getwd() ,since I
am, as he suggested trying to set the variable *path* to my working
directory with path<-"."
Mr. Mittal also recommended importing with r studio, which I shall try in
the meantime.
Many thanks,
Spencer Brackett
