Sun Rui created SPARK-12338: ------------------------------- Summary: Support dropping duplicated rows on selected columns in DataFrame in R style Key: SPARK-12338 URL: https://issues.apache.org/jira/browse/SPARK-12338 Project: Spark Issue Type: New Feature Components: SparkR Affects Versions: 1.5.2 Reporter: Sun Rui
in R, unique() can drop duplicated rows on all columns. And something like {code} df[!duplicated(df[,c('x1', 'x2')]),] {code} is used to drop duplicated rows on selected columns. It's better that my can support duplicated(), and subsetting a DataFrame using the result of duplicated(). -- 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
