问题
I have an excel file with data where the columns are the samples and the rows the attributes. I can't transpose the data, because the rows exceed the maximum number of columns. When I load this data into rapidminer, it automatically sets the columns as attributes and the rows as samples.
How can I set the columns as samples and the rows as attributes?
回答1:
Assuming that you mean that you can't transpose the data in Excel because of the row limitation, the shortest answer is to start your process in RapidMiner with the desired Read operator (Import - Data - Read CSV or Read Excel) and then use the RapidMiner's Transpose operator (Data Transformation - Rotation - Transpose).
Make sure to select "first row as names" in the Read... operator, if appropriate.
