mcps

问题 I'm using adehabitat to create mcps for annual and seasonal ranges. my csv is set up as a binary system for categorizing the seasons. it looks like this across the top: anid - date - easting - northing - annual - seasonA - seasonB - seasonC However, some of my animals do not have enough locations for each season. My first subset looks like this: seasonA <-locations[locations$seasonA==1] And when I make my table: t2<-table(seasonA$anid) t2 I see that some of the animals have less than 30
