Clash Royale CLAN TAG #URR8PPP 'Error: could not find function runmean' from an installed package: caTools? I installed 'caTools' R package through the command line: $ R $ install.packages("caTools", lib="~/R/library") Then, did this command: INPUT=/home/user/file.bam OUTPUT=/home/user/file_cor.bam Rscript run_spp_nodups.R -c=$INPUT -savp -out=$OUTPUT And got the error: Error: could not find function "runmean" Execution halted The function 'runmean' belongs to package I installed, 'caTools'.

Clash Royale CLAN TAG #URR8PPP i18n for Angular 6 using angular cli I've been reading Angular documentation for i18n using the ng tool xi18n . It looks like an impressive tool but I didn't get the following line. xi18n When you internationalize with the AOT compiler, you must pre-build a separate application package for each language and serve the appropriate package based on either server-side language detection or url parameters. does it mean I need to build 100 apps & do the serve depending on the detection I do on server side? Question is, Is it even possible in production scenarios? blog.danieleghidoli.it/2017/01/15/i18n-angular-cli-aot – Chellappan Aug 6 at 7:32 Yes you build one app for every language and need to serve the correct app depending on the language setting. This is because during the compiling process the app gets translated. Using aot means it is pre compiled consequently you need a pre compiled version for every language. Alternativ...

Clash Royale CLAN TAG #URR8PPP How to query secondary replicas in Azure Cosmos DB As per this article, https://docs.microsoft.com/en-us/azure/cosmos-db/distribute-data-globally, each partition consists of four replicas for high availability. Also, I understand that Stored procedures always run against the primary replica (where all writes go). When we use DocumentClient to issue client side queries, there are options to set to query across specific regions. But I am not able to find how to query the secondary replicas. You don't query the secondary replicas. CosmosDB does this for you. You can however provide the ConsistencyLevel as part of you DocumentClient initialisation which will affect the replica querying – Nick Chapsas Aug 5 at 19:08 ConsistencyLevel DocumentClient @NickChapsas Do the queries from Stored procedures also hit the secondary or just the queries from the client side? – vmn Aug 5 at 22:35 I don't think it is done on the cl...
