Getting the Error: All inputs to rbind.fill must be data.frames after upgrade to rmr 3.2

[sravan kumar]

Hi,

I have recently upgraded my RMR version from 3.1 to 3.2 and the leftouterjoin fails with the error Error: All inputs to rbind.fill must be data.frames

It was running fine with RMR version 3.1

My R version is 3.1. It is failing in R 3.0.2 too.

Code snippet for which it is giving me the error.

library(rmr2)

library(rhdfs)

rmr.options(backend = "local")

df1<-data.frame(a=c(1:4),b=c(6:9))

df2<-data.frame(d=c(6:9),e=c(6:9))

input1 <- to.dfs(list(key=df1,val=df2))

df3<-data.frame(a=c(1:3),b=c(6:8))

df4<-data.frame(d=c(1:3),e=c(1:3))

input2 <- to.dfs(list(key=df3,val=df4))

reducer = function(key, left, right) {

    if(!class(right)=="data.frame")

        output.val=left

    else

        output.val=right

    keyval(key,left)

}

output<-equijoin(

    left.input = input1, 

    right.input = input2, 

    outer = c("left"),    

    reduce  = reducer)

Thanks for this report and the self contained test case, that's a model of how to report a problem. This is now bug 144. Please follow any progress there.

Thanks Antonio, for the quick reply and for raising the bug. Is there any work around for the these outerjoins in the latest version?

This was actually reported and fixed. Not sure what's going on. Please let's not have two threads on this, this is now on the issue tracker.
