New R version - Issue with as.vector coercion on data.frame
Hi I recently upgraded to the latest r version and got an issue with the command as.vector() on a data.frame object. With the previous R version the returned object was a vector but now it is formatted as a list (see below)
futures_quotes
SMI Future SMIM Future Euro Stoxx 50 Future S&P 500 Mini Future FTSE 100 Future Nikkei 225 Future 1 11999 2871 3692 4150 7419 26853
class(futures_quotes)
[1] "data.frame"
as.vector(futures_quotes[1,1:3])
$`SMI Future` [1] 11999 $`SMIM Future` [1] 2871 $`Euro Stoxx 50 Future` [1] 3692
class(as.vector(futures_quotes[1,1:3]))
[1] "list" Can you help me on this ? (I solved the issue temporarily with as.vector(t(futures_quotes[1,1:3])) Kind regards Marc Weibel <http://www.enisopartners.com/> Dr. Marc Weibel CIO & Partner Tel: +41 44 286 17 02 Mob: +41 78 892 96 55 E-Mail: marc.weibel at enisopartners.com <mailto: marc.weibel at enisopartners.com> Eniso Partners AG Claridenstrasse 34 | Postfach | 8022 Z?rich <https://www.linkedin.com/in/marc-weibel-29a396/> Based on previous e-mail correspondence with you and/or an agreement reached with you, Eniso Partners considers itself authorized to contact you via unsecured e-mail.
