Hi,
I'm getting an error message:
Error in df[, 1:4] * df[, 5] : non-numeric argument to binary operator
In addition: Warning message:
Incompatible methods ("Ops.data.frame", "Ops.factor") for "*"
here is my code:
##reading in the file
happyguys<-read.table("c:/test4.dat", header=TRUE, row.names=1)
##subset the file based on Select If
test<-subset(happyguys, PROV==48 & GRADE == 7 & Y_Q10A < 9)
##sorting the file
mydata<-test
mydataSorted<-mydata[ order(mydata$Y_Q10A), ]
print(mydataSorted)
##assigning a different name to file
happyguys<-mydataSorted
##trying to weight my data
data.frame<-happyguys
df<-data.frame
df1<-df[, 1:4] * df[, 5]
##getting error message here??
Error in df[, 1:4] * df[, 5] : non-numeric argument to binary operator
In addition: Warning message:
Incompatible methods ("Ops.data.frame", "Ops.factor") for "*"
Does anyone know what this error message means?
I've been reviewing R code all day & getting more familiar with it
Thanks,
Nat
