[R] Warning message help
I am trying to great a new column of effort data from an existing vector of gears used. It is a simple code where effort[Gear==300]=(DIST_TOW*7412) effort[Gear==301]=(DIST_TOW*7412) The code appears to work for some of the data but fails for others and inserts a NA value I also get this warning message Warning message: number of items to replace is not a multiple of replacement length Can anybody tell me what this means. thanks Cameron Guenther Associate Research Scientist FWC/FWRI, Marine Fisheries Research 100 8th Avenue S.E.

Re: [R] Warning message help
Shouldnt that be effort[Gear==300]<-(DIST_TOW*7412) I think we're going to need to see some sample datasets to tell you any more.

Re: [R] Warning message help
Cameron Assuming DIST_TOW is a vector of the same length as effort and Gear, is this what you mean? effort[Gear==300] = DIST_TOW[Gear==300]*7412 MHP on 11/21/2005 10:44 AM Guenther, Cameron said the following: >I am trying to great a new column of effort data from an existing vector >of gears used. >It is a simple code where > >effort[Gear==300]=(DIST_TOW*7412) >effort[Gear==301]=(DIST_TOW*7412) > >[...] > > -- Michael Prager, Ph.D. Population Dynamics Team, NMFS SE Fisheries Science Center NOAA Center for Coastal Fisheries and Habitat Research Beaufort, North Carolina 28516 http://shrimp.ccfhrb.noaa.gov/~mprager/ Opinions expressed are personal, not official.
