[英]Save file with variable text in file name in R
in R I'm trying to read in a file name where part of the file name references a string variable.在 R 中,我试图读入一个文件名,其中部分文件名引用了一个字符串变量。 I'm having issues with the paste function.我的粘贴功能有问题。
Without the variable reference I was reading the file as follows:在没有变量引用的情况下,我正在读取文件,如下所示:
adp <- readxl::read_xlsx('Data//2020-08-28 Hours.xlsx')
I also have the following variable:我还有以下变量:
pdate <- as.Date('2020-08-28')
I tried to incorporate the variable as follows, but something is wrong with my syntax:我尝试按如下方式合并变量,但我的语法有问题:
adp <- readxl::read_xlsx(paste(''Data//'. pdate, 'Hours.xlsx'')
这是正确的语法:
readxl::read_xlsx(paste0('Data//', pdate, ' Hours.xlsx'))
