removing columns via subset throws unary invalid argument error
1
I have a dataframe with rather odd column names (it is a combination of several other dataframes). Every time I try to subset and remove a column it gives me an error Error in -c("surveys$gender") : invalid argument to unary operator. Can someone explain why this is happening?
df1<-NULL
df1$a<-c(1,2,3,4,5)
df1$b<-c(4,5,2,6,1)
df1$c<-c(0,9,0,6,3)
surveys<-NULL
surveys$gender<-c(0,0,0,1,1)
df1<-as.data.frame(df1)
df1<-cbind(df1,surveys$gender)
male<-subset(df1,'surveys$gender'<1,select=-c('surveys$gender')) #trying to get only 0 and remove the gender column from the result
r subset

you don't need quotes in subset here

Change your subset line to:
df1 <- NULL
df1$a<-c(1,2,3,4,5)
df1$b<-c(4,5,2,6,1)
df1$c<-c(0,9,0,6,3)
df1$gender<-c(0,0,0,1,1)
male <- subset(df1, gender < 1, select = -gender)
That is, use bare column names rather than quotes.

Usecbind(df1,surveys["gender"])- there's no reason to have such an odd looking variable name.

Change your subset line to:
df1 <- NULL
df1$a<-c(1,2,3,4,5)
df1$b<-c(4,5,2,6,1)
df1$c<-c(0,9,0,6,3)
df1$gender<-c(0,0,0,1,1)
male <- subset(df1, gender < 1, select = -gender)
That is, use bare column names rather than quotes.
