gather with tidyr: position must be between 0 and n error
13,924
Solution 1
x.row10 %>% gather(Year, Val, c(2:8))
Solution 2
The question is marked as solved, but I think it may be useful to post my answer. The way David Arenburg does is right. You need exact backticks for it to work. If you use the quotation marks as @uncool in the comments did, you get the same error like him:
Error: All select() inputs must resolve to integer column positions.
The following do not:
* c("2004":"2009", "2012")
For the German keyboard users: If you don't know how to type backtick (like me a few minutes ago):
"Shift + the key on the right side of ß" and, after that, "spacebar".

I have some data like below:
x.row10 <- setNames(data.frame(letters[1:3],1:3,2:4,3:5,4:6,5:7,6:8,7:9), c("names",2004:2009,2012)) # names 2004 2005 2006 2007 2008 2009 2012 #1 a 1 2 3 4 5 6 7 #2 b 2 3 4 5 6 7 8 #3 c 3 4 5 6 7 8 9
Now I can make them long with
gather()
from thetidyr
package by writing:x.row10 %>% gather(Year, Val, -names)
But when I use
x.row10 %>% gather(Year, Val, c(2004:2009,2012))
which is my intuitive choice, I get the error message
Error: Position must be between 0 and n
How come and how can this be resolved?
