Hello, I would like to remove the last 8 digists of character strings in a vector. Below I added a couple of elements from that vector.
I have a problem defining a pattern to replace the digits using for example "sub". Removing the ".tif" part works fine using sub('.tif',"",x), but how do I get rid of the four preceding digits? Thanks for your help, Kim Input: [3988] "060907_17_3_5_1_1_2909.tif" "060907_17_3_5_2_1_2910.tif" "060907_17_3_5_3_1_2911.tif" [3991] "060907_17_3_5_4_1_2912.tif" "060907_17_3_5_5_1_2913.tif" "060907_17_3_5_6_1_2914.tif" Desired output: [3988] "060907_17_3_5_1_1_" "060907_17_3_5_2_1_" "060907_17_3_5_3_1_" [3991] "060907_17_3_5_4_1_" "060907_17_3_5_5_1_" "060907_17_3_5_6_1_" __________________________________________ Kim Milferstedt University of Illinois at Urbana-Champaign Department of Civil and Environmental Engineering 4125 Newmark Civil Engineering Laboratory 205 North Mathews Avenue MC-250 Urbana, IL 61801 USA phone: (001) 217 333-9663 fax: (001) 217 333-6968 email: [EMAIL PROTECTED] http://cee.uiuc.edu/research/morgenroth ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
