error in LSA segmentation! #5

Closed hanlinzhougit closed 2 years ago

hanlinzhougit commented 3 years ago

Hi, this is a good work. When I used MEDALT, i have meet this error. LOG is as follow:

[1] Visualization MEDALT! null device 1 [1] LSA segmentation! Error in scan(file = file, what = what, sep = sep, quote = quote, dec = dec, : scan() expected 'an integer', got '2148562433' Calls: eval ... import -> .local -> DataFrame -> read.table -> scan Execution halted

"2148562433" this number is at the 3564 line in my input file. And my input file is more than 5k lines. Then I used the first 3k lines from my input file into a new file, the new file can be worked by MEDALT.

Any Idea on why this is happening and how can be fixed? Thank you a lot!

Best Regards

Hello,

My guess is that it has nothing to do with the number of lines, but that the maximum integer supported by R is 2147483647 < 2148562433. I'm not sure if there is a quick and clean fix for that, but you might consider dividing all values in your csv by 2 (and round to the nearest integer).
