Hi Y'all,
I am using the text mining package (tm). I am trying to filter out all of the
words in a Term Document Matrix that are not in a list of words that I am
interested in. I am using the following code:
z<-tm_intersect(txt.dtm, c("communications", "safety", "climate", "blood",
"surface", "cleanliness", "amenities", "monitoring", "staff", "competency",
"policy", "procedure", "inconsistency", "physician", "orders", "treatment",
"times", "care", "plan", "strategies", "concerns", "meetings", "equipment",
"treatment", "options", "delivery", "care", "discharge", "welfare",
"violations", "HIPPS", "professionalism", "lack", "boundaries crossing",
"transportation", "benefits", "assistance", "beneficiary", "complaint",
"grievance", "inquiry", "formal", "data", "processing", "concern", "facility",
"abuse", "data", "request", "disruptive", "information", "patient",
"discharge", "transfer", "physical", "ethics", "resolution",
"professional","reimbursement", "financial", "request", "status",
"educational", "material", "forms", "technical", "assistance", "staff",
"related", "quality",
"care","disruptive","behavior","special","needs","mental","illness","noncompliance","illegal",
"immigrant!
", "abusive", "violent","litigation", "prisoner", "corporate", "lockout",
"disposition", "discharge", "reason"))
I get the following error:
"no applicable method for 'tm_intersect' applied to an object of class
"c('TermDocumentMatrix', 'simple_triplet_matrix')" "
What am I doing wrong? I'd greatly appreciate any ideas or thoughts on
this!!!! Thank you!!
