text mining problem using TM package
...local meta data.
Here is the code:
*data <- ("C:/… /19970331")*
* *
* *
*rs <- ReutersSource(data , encoding = "UTF-8")*
*RC <- VCorpus(DirSource(data), readerControl = list(reader =
readRCV1asPlain,*
*
language = "en_US",*
*
load = TRUE),*
*
dbControl = list(useDb = TRUE,*
*
dbName = "texts.db",*
*
dbType = "DB1"))*
* *
* *
* *
*tm_index(RC, FUN = sFilter, doclevel = F, useMeta = T, "Topics == 'MCAT'")
*
* *
* *
When I use sFilter, I can only filter fields in yellow, I want to filter...
