str_count实现这一目标，但没有帮助。我在 STO 中发现了许多与 Q 相关的字数统计，但在 R 中没有发现列表类型。
dd<-lapply(O,function(x) c<-str_count(x))
O <- structure(list(text= list(c("access", "access","access", "access"),
c("report","access", "access", "access"),
c("access","access", "access", "access"),
c("access","access", "access", "access"),
c("access"),
c(character(0)),
c("report", "report", "access", "access","report", "report", "report", "report", "report", "report",
"data", "data", "report", "access", "report", "report"),
c("report", "access","access"),
c("report"), c("report", "access", "access", "access", "report","access"))))
frq1 <- findFreqTerms(O)不工作
最佳答案
好的，告诉我这对你有什么作用。
使用这些数据:
O <- structure(list(text.1 = list(character(0), c("access", "access",
"access", "access")), text.2 = list(character(0), c("report",
"access", "access", "access")), text.3 = list(character(0), c("access",
"access", "access", "access")), text.4 = list(character(0), c("access",
"access", "access", "access")), text.5 = list(character(0), "access"),
text.6 = list(character(0), character(0)), text.7 = list(
character(0), c("report", "report", "access", "access",
"report", "report", "report", "report", "report", "report",
"data", "data", "report", "access", "report", "report"
)), text.8 = list(character(0), c("report", "access",
"access")), text.9 = list(character(0), "report"), text.10 = list(
NULL, c("report", "access", "access", "access", "report",
"access"))), .Names = c("text.1", "text.2", "text.3",
"text.4", "text.5", "text.6", "text.7", "text.8", "text.9", "text.10"
))
text.x 的第二个元素中列表，我们会将这些单词放入
newlist .更重要的是，我们会将这些数据转换为因子，以便稍后将它们重新组合成一个数据框。
newlist <- list()
for(item in O) {
newlist[[length(newlist)+1]] <- factor(item[[2]], levels = c("access", "data", "report"))
}
dd <- data.frame(lapply(newlist, table))
dd <- t(as.matrix(dd[,c(2,4,6,8,10,12,14,16,18,20)]))
rownames(dd) <- paste0("Text.",1:10)
colnames(dd) <- c("access", "data", "report")
dd
# access data report
