if "data" was your data.frame, data[4:length(data)] was also a
data.frame.
but, c(data[4:length(data)] ) coerces it to a list.
therefore coppie is a list.
coppie[1] is also a list of length 1...
compare that to: coppie[[1]]

Ciao Paolo,
You were asking for the length of the first element of the vector
coppie, which is of course 1. Did you mean to say lgngth(coppie)?
length(data[,4]) is asking how many elements in that column, which
seems to be 5. also your statement
coppie <- c(data[4:length(data)])
seems strange. What did yo

I think that coppie is a list, so
length(coppie[[1]])

Ciao Paolo,
How about you show some row of your data?
How many columns have your data.frame? One?
By the way "data" is not a so good name for your data frame.
We will be very happy to help you
Kindly,

Hi all
I have this problem:
In my database .dta, called "data" I have five rows
data<-read.dta("C:\\2_CO_mmobile_ALL_Rid.dta")
# From this database I wuold like to create another
coppie<-c(data[4:length(data)])
but I find this
# Length of original data
length(data[,4]
7 matches
