Фильтрация дат для графика временных рядов с использованием dplyr

/ 22 мая 2018

Я пытаюсь отфильтровать свой набор данных, чтобы в нем были только строки за 1996-2015 годы и только столбцы orgid, stdate, locid, charnam.Весь набор данных содержит годы с 1988 по 2015 год и множество разных столбцов.Я только недавно узнал о пакете dplyr и подумал, что это будет путь.Однако я продолжаю получать эту ошибку, и я не понимаю, почему я ее получаю.Ошибка, которую я продолжаю получать: Error in is_character(x) : object 'rlang_is_character' not found

Это мой код: 

    ########## download necessary packages to make script run #########################################################################
if (!require(pacman)) {
  install.packages('pacman')

}

pacman::p_load("tidyverse")
#### Read in the necessary data ######
roadsalt_data<-read.table("QADportaldata_1988-2015.tsv",header=T,sep="\t",fill=T,stringsAsFactors = F)
#Convert date column from a character class to a date class so ggplot can  display as a continuous variable ###
roadsalt_data$stdate <- as.Date(roadsalt_data$stdate)
## Filter dataset to only contain years 1996-2015 ########
roadsalt_data_sub<-roadsalt_data %>%
                     select(orgid,stdate,locid,charnam) %>%
                     filter(between(roadsalt_data, as.Date("1996-01-01"), as.Date("2015-07-01")))

Вот предварительный просмотр набора данных:

Любая помощь будетс благодарностью!Заранее спасибо!

Если я правильно помню, between() не работал с Date с в один момент, даже когда аргументы left и right были конвертированы с as.Date().

Вотнесколько альтернатив.Поскольку все ваши выборочные данные попадают в промежутки между указанными годами, все они фильтруют даты между 2013-02-04 и 2013-02-12.Отрегулируйте соответствующим образом.

Если вы устали бороться с tidyverse адом зависимости, вы можете попробовать data.table вместо этого: 

library(data.table)

## Convert to a data.table by reference
setDT(roadsalt_data) 

## Filter on date and only return a subset of columns
roadsalt_data[between(stdate, as.Date("1996-01-01"), as.Date("2015-07-01")), .(orgid,stdate,locid,charnam)]
