Hi, We are using open source license of R to analyze data at our organization. The system configuration are as follows:
* System configuration: o Operating System - Windows 7 Enterprise SP1, 64 bit (Desktop) o RAM - 8 GB o Processor - i5-6500 @ 3.2 Ghz * R Version: o R Studio 1.0.136 o R 3.4.0 While trying to merge two datasets we received the following resource error message on running the code Code: merg_data <- merge(x=Data_1Junto30Jun,y=flight_code,by.x="EB_FLNO1",by.y="EB_FLNO1",all.x = TRUE) Error Message: Error: cannot allocate vector of size 5.8 Gb Later we tried running the code differently but error still remained Code: merg_data <- sqldf("Select * from Data_1Junto30Jun as a inner join flight_code as b on a.EB_FLNO1=b.EB_FLNO1") Error Message: Error: cannot allocate vector of size 200.0 Mb We have upgraded the RAM to 8 GB couple of months back. Can you let us know options to resolve the above issue without having to increase the RAM? The size of the datasets are as follows: * Data_1Junto30Jun (513476 obs of 32 variables). Data size - 172033368 bytes / 172 MB * flight_code (478105 obs of 2 variables). Data size - 3836304 bytes / 4 MB Help with determining system requirement: Is there a way to determine minimum system requirement (hardware and software) depending on size of the data, the way the data is loaded into R (directly from server or in a flat file) and the type of analysis to be run? We have not been able to get any specific information related to this and are estimating the requirements through a trial and error method. Any information on this front will be helpful.
