Apache Spark commented on SPARK-13905: -------------------------------------- User 'sun-rui' has created a pull request for this issue: https://github.com/apache/spark/pull/11726 > Change implementation of as.data.frame() to avoid conflict with the ones in > the R base package > ---------------------------------------------------------------------------------------------- > > Key: SPARK-13905 > URL: https://issues.apache.org/jira/browse/SPARK-13905 > Project: Spark > Issue Type: Improvement > Components: SparkR > Affects Versions: 1.6.1 > Reporter: Sun Rui > > SparkR provides a method as.data.frame() to collect a SparkR DataFrame into a > local data.frame. But it conflicts the methods with the same name in the R > base package. > For example, > {code} > code as follows - > countData <- matrix(1:100,ncol=4) > condition <- factor(c("A","A","B","B")) > dds <- DESeqDataSetFromMatrix(countData, DataFrame(condition), ~ condition) > Works if i dont initialize the sparkR environment. > if I do library(SparkR) and sqlContext <- sparkRSQL.init(sc) it gives > following error > > dds <- DESeqDataSetFromMatrix(countData, as.data.frame(condition), ~ > > condition) > Error in DataFrame(colData, row.names = rownames(colData)) : > cannot coerce class "data.frame" to a DataFrame > {code} > The implementation of as.data.frame() in SparkR can be improved to avoid > conflict with those in the R base package. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
