У меня есть символьный вектор, который в некоторых случаях может содержать несколько примеров, в которых следующие регулярные выражения сопровождаются значением цифры c и затем закрываются. Вот пример:
form4_2 <- "<transactionPricePerShare><value>31.43</value>"
Я хотел бы иметь возможность собрать значения "31,43" и любые другие значения чисел c между другими примерами совпадающей строки, содержащейся в векторе символов, а затем создать фрейм данных с результатом. Любая помощь будет оценена.
library('stringr')
form4_3 <- form4_2[which(str_detect(form4_2,"</transactionPricePerShare>")=='TRUE')-1]
form4_3 <- str_remove(form4_3,'<value>')
form4_3 <- str_remove(form4_3,'</value>')
form4_4 <- data.frame(as.numeric(form4_3))
colnames(form4_4) <- "Transacted Price ($)"
