Problem : I am very new to R programming. Currently I am learning R programming. I have below two tables I have asembled them via cbind(). My first Table table_alpha is as below: x1 col1_x1 col2_x1 A "1999 12 01 00:00" " 0.4" " 0" B "1999 12 02 00:00" " - ... = table_num[,1], fill=-9999) Please find below the error: “Error in fix.by(by.x, x) : 'by' must specify uniquely valid columns”.
