I have a data frame frugivore.abundance.S1 where some columns are factors and
others are numbers.For example these are my independent variables and "density"
is my dependent variable. census<-c(1:70)sites<-c(1:5)birds<-c(1:45)
I want to select the data where sites is 1 and birds are 1,23,24 or 29
So I write:fa1<-frugivore.abundance.S1attach(fa1)(abund.frug.RN1<-fa1[sites==1
& birds==c(1,23,24,29),])
This code doesn't print all the data it should for some reason. It seems to not
print rows where "density" has the same value as another row with the same
criteria.
i.e. if in the original data we have the following then only rows 1 and 3 will
be printed, not all of them:
census sites birds density1 1 1 0.0032
1 1 0.0033 1 1
0.001
Can anyone help me out with this please?
