readxl question
Hi Are you sure that your command read values from respective cells? I tried it and got empty data frame with names
WO <- lapply(files, read_excel, sheet=1, range=("B3"))
as.data.frame(WO)
[1] ano TP303 X96
[4] X0 X3.7519999999999998 X26.7
<0 rows> (or 0-length row.names)
To get data, col_names argument should be set to FALSE
WO <- lapply(files, read_excel, sheet=1, range=("B3"), col_names=FALSE)
WO2 <- lapply(files, read_excel, sheet=1, range=("B5"), col_names=FALSE)
After that unlist and one rbind together with t should be enough to give you
one table
WO <- unlist(WO)
WO2 <- unlist(WO2)
result <- t(rbind(WO, WO2))
result
WO WO2
...1 "ano" "ano"
...1 "TP303" "261119/2"
...1 "96" "288"
...1 "0" "192"
...1 "3.752" "25.92094"
...1 "26.7" "38.6"
And instead txt document you could do write.table(result, "result.xls", sep = "\t", row.names = F) And now "result.xls" is directly readable with Excel Cheers Petr

layout.
The problem is that the data in each Excel data is not in rectangular
form. I've
been using readxl to extract the data which I need. Each of my metrics are stored in a particular cell. For each metric, I
create text
files which stores my metrics.
library(plyr)
library(readxl)
files <- list.files(pattern="*.xls", full.names = FALSE)
# Extract Work Order
WO <- lapply(files, read_excel, sheet="Sheet1", range=("B9")) WO_list <-
as.data.frame(WO) trans_WO <- t(WO_list) write.table(trans_WO ,"WO.txt")
# Extract bubble 14_1
BUBBLE_14_1 <- lapply(files, read_excel, sheet="Sheet1", range=("c46"))
BUBBLE_14_1_list <- as.data.frame(BUBBLE_14_1)
trans_BUBBLE_14_1 <- t(BUBBLE_14_1_list)
write.table(trans_BUBBLE_14_1,"BUBBLE_14_1.txt")
# Extract bubble 14_2
BUBBLE_14_2 <- lapply(files, read_excel, sheet="Sheet1", range=("c62"))
BUBBLE_14_2_list <- as.data.frame(BUBBLE_14_2)
trans_BUBBLE_14_2 <- t(BUBBLE_14_2_list)
write.table(trans_BUBBLE_14_2,"BUBBLE_14_2.txt")
After the text files have been created, I cut and paste the contents of
each
text file to Excel. This has worked fine if the number of cells I am extracting from a file is
small.
If the number gets larger, this method is inefficient. Any advice on how to do this would be appreciated. All the best, Thomas Subia [[alternative HTML version deleted]]
