Colleagues,
I am using readxl to extract a serial number and its associated data using the
following code.
library(readxl)
files <- list.files(pattern="*.xls", full.names = FALSE)
serials <- lapply(files, read_excel, sheet="Flow Data", range=("c6"))
flow.datum <- lapply(files, read_excel, sheet="Flow Data", range=("c22:c70"))
dates <- lapply(files, read_excel, sheet="Flow Data", range=("h14"))
Here each serial and date is associated with 49 data points in flow.datum.
Now I write the serials, flow data and dates into a text file using:
datesdf <- as.data.frame(dates)
mydates <- list(datesdf)
write.table(mydates,"dates.txt",sep="\t")
serialdf <- as.data.frame(serials)
myserials <- list(serialdf)
write.table(myserials,"serials.txt",sep="\t")
flowdf <-as.data.frame(flow.datum)
myflow <- list(flowdf)
write.table(myflow,"myflow.txt",sep=",")
The problem with the dates.txt and the serials.txt is that they need to
associated with its 49 corresponding values in myflow.txt.
The objective is to create a text file having this format:
Serial Date Flow
I'm not sure how to do this. Any suggestions would be appreciated.
