Hi there, I faced a weird problem doing a seemingly simple task in R. Specifically, when trying for reading an RDS file from the working directory, the following error is appeared. Code: records <- readRDS("tweets.rds") Error: Error in readRDS("tweets.rds") : error reading from connection In addition: Warning message: In readRDS("tweets.rds") : invalid or

Wouldn't the obvious problem be that your data file is corrupted or was never created using saveRDS in the first place? Can you show us a complete example of creating and attempting to read what was just created?

I''m attempting to use the example given in the Rails Recipes book chapter 2, to create a select drop-down using the InPlaceEditor function (modified to be InPlaceSelectEditor.

Hello, Arel::SelectManager (arel 2.0.9) uses following statement to insert a new record: @engine.connection.insert im.to_sql, ''AREL'', primary_key_name, primary_key_value But in DatabaseStatements insert ist defined as: insert(sql, name = nil, pk = nil, id_value = nil, sequence_name = nil) Actually, Arel::SelectManager does not use the sequence name.

Hey, We hit a bug today because Arel::Visitors::ToSql is not threadsafe. Here is what is happening: Arel::Visitors::ENGINE_VISITORS is a cache of visitors instances. These instances are not inherently threadsafe because it contains state ''@last_column'', ''@connection'' that is shared between threads. The other variables ''@pool'',

I trying to create a select using Arel but I''m passing three parameters, I want to include the parameters only if they are different to nil or blank.

Hi all, I''ve been playing around with Arel this week (actually outside of Rails) and found an issue with the clone implementation. I''ve added a patch and a testcase here: https://github.com/codders/arel/commit/660f706491ac012cb133554cffeaa6b9ae6046e9 and made a pull request against the rails/arel repo. I''ve also been playing around with support for ordering on
