I keep getting this error whenever the works pull a job from the Redis queue. I thought it might be my foreach function but I get the same error when I run the example code:

Error in names(z) <- w[o] :
'names' attribute [69] must be the same length as the vector [68]

Here is my console output:

Main:

registerDoRedis('works')
getDoParWorkers()
[1] 2
foreach(j=1:10,.combine=sum,.multicombine=TRUE) %dopar% {

  • 4*sum((runif(1000000)^2 + runif(1000000)^2)<1)/10000000
  • }
    [1] "interrupt: \n"
    Error in tryCatchOne(expr, names, parentenv, handlers[[1L]]) :
    attempt to apply non-function
    In addition: Warning message:
    In e$fun(obj, substitute(ex), parent.frame(), e$data) :
    Queue length off by 10...correcting

Worker:

require('doRedis')
redisWorker('works')
Waiting for doRedis jobs.
Processing job 3 from queue works
Error in names(z) <- w[o] :
'names' attribute [69] must be the same length as the vector [68]

Any foreach function I try results in the same error. I am on OSX.

The problem might be colons in the INFO string returned by Redis. I wrote a patch to rredis whcih appears to fix the problem

Sorry for the latency, just back to work. patcpsc graciously fixed the problem in rredis, which I have merged and am in the process of submitting to CRAN tonight!

In the short term you could install from github with:

install.packages("devtools")  # if you dont' already have this
library("devtools")
install_github("rredis","bwlewis",quick=TRUE)
library("rredis")
# ...

Should be on CRAN in a few days. The fixed version on CRAN will be called 1.6.9.

Best,

Bryan

Thanks! It will take me a couple of days to get to this
