Hi users,
I have a simple vector of five coordinates in form of ('lat1,
long1','lat2,long2',...,'latn,longn')
And I would like to create two vectors, one just with the first coordinate
G1<-c('lat1,'lat2',..,'latn')
G2<-c('long1,'long2',...,'longn')
I am trying to apply strsplit(x=g,split=',') on my object g, but it is
not working, any help?
I struggle to understand how to use the regular expressions.
structure(c(32L, 38L, 40L, 34L, 27L), .Label =
c("-17.394217,15.886574",

Subject: [R] Splitting coordinates into two
Hi users,
I have a simple vector of five coordinates in form of ('lat1,
long1','lat2,long2',...,'latn,longn')
And I would like to create two vectors, one just with the first coordinate
G1<-c('lat1,'lat2',..,'latn')
G2<-c('long1,'long2',...,'longn')
I am trying to apply strsplit(x=g,split=',') on my object g, but it is
not working, any help?
I struggle to understand how to use the regular expressions.
