<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />hi all
iam trying to calculate the difference between tow days using JSL..i have a script where I extract rows from an excel sheet that has the column value 0. After extracting the required rows, I want to calculate the differnce between tow dates and place the value in a new column. my script goes like this:
dt = data table("Final Sheet");
match_rows = dt << get rows where( :Column Type == 0 );
dt << subset(columns(), rows(match_rows));
Output Table("DateSheet");
can some one help me how I can add a column in the final output sheet and then calcuate the difference between the tow dates which are in columns E and C.
I thank all the JMP users for helping me out in JSL scripting..iam very new to JSL.
In JMP, help>books>scripting guide. Either search for "new column" or navigate the second of the 2 indexes to N and from there to "new column". You will see some examples of creating a new column in JSL which contains a formula. Since JMP dates are in seconds from 1/1/1904, the difference between two dates is in seconds. Divide by 60 to get the number of minutes, 60*60 for the number of hours, or divide by 60*60*24 to get the number of days.
new column("Duration in Days", Formula((:E-:C)/(60*60*24)))
