Date is not currently supported in colClasses or colInfo, but Date variables can be created by importing string data and converting to a Date variable using as. If a numeric vector, its elements are taken as the indices of columns to quote. A directory will be created whose name is the same as the.

We can just specify a vector of variable names to convert as the factorInfo:. A crucial step in many analyses is transforming the data into a form best suited for the chosen analysis. Since the resulting data set will clearly fit in memory, we omit the outFile argument and assign the result of the data step, then use rxGetInfo to see our results as usual: This can be overridden by specifying “character” in colClasses and colInfo.

In addition rxTextToXdf currently requires that all rows of data in the text file contain the same number of entries. For example, to compress all the. If TRUEan existing outFile will be overwritten, or if appending columns existing columns with the same name will be overwritten. If you conveft to share data with others not using.

We will keep only the rows where the remainder after dividing the row number by 10 is 0: In both cases, row and column names are quoted if they are written. The value 0 specifies no compression. You can create an XDF using any data that can be loaded by rxImportand by specifying an outFile consisting of a file path to a writable directory. Use the function rxSplit to split your data. Here we will use the sample data set containing daily information on the Dow Jones Industrial Average.

The following call to rxDataStep will accomplish all of the above, returning a new data frame with the transformed variables:.

Microsoft Corporation Microsoft Technical Support. On Linux, you can type Revo64 at the command line.

Note that we can’t provide technical support on individual packages. It then passes the variables needed for data transformations back to R for manipulation:. Value An RxTextData object representing the output text file. Post as a guest Name. Using a rowSelection expression and list of varsToKeepwe can extract the ageperwtand sex variables for individuals over the age of 40 living in Washington State: Encoding Details If the input data source or file contains non-ASCII character information, please use the function rxImport with the encoding settings recommended in the RxImport documentation under ‘Encoding Details’ Note For reasons of performance, rxTextToXdf does not properly handle text files that contain the delimiter character inside a quoted string for example, the entry “Wade, John” inside a comma delimited file.
