Error in asfn(rs[[i]]) : need explicit units for numeric conversion

Question

Hi
I am using the sqldf package in R to do some joins of my data table as follows:
p1<-sqldf("SELECT t3.* FROM p as t3 JOIN (SELECT userid, MAX(type) as LastActivityType FROM p GROUP BY userid) t4 ON t3.userid = t4.userid AND t3.type = t4.LastActivityType")
However , I am getting the error mentioned in the subject line
The error doesn't appear  when I change the column names from t3.* and limit it to a subset of column names ( t3.userid, t3.LastActivity....).
Surprisingly though, I have another similar sql script in the same code block which runs just fine.
My code runs fine in RStudio, so I guess there's some incompatibility with the Azure environment somewhere. For reference, the sqldf package and its dependencies (imported separately as a zip) is compatible with R  3.1.2
Can someone help me solve this? 
Thanks in advance!!

Hi AK
Thanks for the quick response 
So I checked the following:
1) Downloaded the dataset from AML from the step just previous to where my sql script appears, fed it into RStudio with stringsAsFactors=FALSE and thereupon ran the sql script. It works without any issues. It works fine if I dont set stringsAsFactors
as false as well
2) Checked the CRAN documentation on the sqldf package, it mentions that the package is valid for versions>=R3.1.0
3)All 4 dependencies were included. Only one was preinstalled. The output log says: 
warning: package 'proto' is in use and will not be installedso I removed the package 'proto' just in case it was causing trouble.Nothing Works :/I am pasting the output log, could you have a look and see if I am missing anything obvious?Thanks a ton!UpasanaOutput Log:Record Starts at UTC 11/27/2014 07:38:27:
