Dear R helpers
I have a city.csv file as given below.
'city.csv'
city_name1 city_name2
New York City Buffallo
So I define
city_name = read.csv('city.csv')
city1 = city_name$city_name1
city2 = city_name$city_name2
My problem is how do I repeat the names one after other say 10 times i.e. my
output should be like
New York
City Buffallo
New York
City Buffallo
New York
City Buffallo
New York City
...................
...................
...................
...................
I have tried the following commands
rep(c(city1,city2), 5)
and I got the output something like this
[1] 1 1 1 1 1 1 .......
If I try
rep((city1,city2), 5)
Error: unexpected ',' in "rep((city1,"
Please guide
Regards
MAdhavi

Hi, Take a look at rep(), specifically the each = parameter. cheers, Paul Madhavi Bhave wrote:> Dear R helpers > > I have a city.csv file as given below. > > 'city.csv' > city_name1 city_name2 > New York City Buffallo > > So I define > > city_name = read.csv('city.csv') > city1 = city_name$city_name1 > city2 = city_name$city_name2 > > My problem is how do I repeat the names one after other say 10 times i.e. my output should be like > > New York > City Buffallo > New York > City Buffallo > New York > City Buffallo > New York City > ................... > ................... > ................... > ................... > > I have tried the following commands > > rep(c(city1,city2), 5) > > and I got the output something like this > > [1] 1 1 1 1 1 1 ....... > > If I try > > rep((city1,city2), 5) > > Error: unexpected ',' in "rep((city1," > > Please guide > > Regards > > MAdhavi > > > Your Mail works best with the New Yahoo Optimized IE8.

Hi! I'm kind of a newboe here, but I think it is because read.csv transforms the character variables to factors. Maybe try setting the argument "as.is" in read.csv(). Or try: rep(as.character(c(city1, city2)),5) That should work.
