[R] Possible bug in direct.evidence.plot?

[Miland Joshi]

Hello

In R when I looked at the class of nb1 I got:
> class(nb1)
[1] "netmetabin" "netmeta"

which suggests that netmeta might work but netmetabin may cause problems. I'll notify Mathias Harrer!

The explanation is likely that class(x) returns a character vector of length > 1.
If you go into the code you can achieve what is probably intended without triggering this error by replacing that statement with the following:

if (inherits(x,"netmeta")) ...

HTH,

I succeeded in getting netmetabin to work, but when trying to use direct.evidence.plot I ran into a problem:

Error in if (class(x) != "netmeta") { : the condition has length > 1

I tried updating netmeta and dmetar (and dmetafor) from R, but the problem remains.
Has anyone come across this, and could it be a bug?
