I have read past SO questions about this and their example as to why we need to use <- not = does not seem applicable (at least in the recent versions).
median(x = 1:10) # Should give an error but both work just fine.
x
median(x <- 1:10)
x
I always use =, BUT seem to finally found a case where <- is necessary but don't understand why, can anyone tell me why <- is necessary here and = does not work. Thank you.
x=c(2,4,6)
names(x)=c('a','b','c')
x
# OR we can do this, but it requires a <-
x='names<-'(x, value=c('a','b','d'))
x='names='(x, value=c('a','b','d')) #Error: could not find function "names="
x
