[R] Read .xlsx and convert date-column value into Dataframe
Hi, Here i am having a .xlsx file and it contains various columns including date-column[mm/dd/yy]-but it is not in the date format. I have to read this excel[.xlsx] file and need to get in dataframe. So i used xlsx-liabrary and it was fine to read data. But the problem is, values in the date column is converting to some other value. for eg:- FF DATE --- 3/31/2016 2/26/2016 -- 1/2/2016 [Values like -- will come in the column to indicate that there is no date mentioned ] and i getting result like this, FF DATE --- 42460 42426 42125 this is the code i am using for it, theData-data.frame(read.xlsx2(InputFilePath, sheetIndex, sheetName=Workflow_Report, startRow=3,colIndex=NULL, endRow=NULL, as.data.frame=TRUE, header=TRUE)) Aim :- I have to get actual date-column values in dataframe from xlsx file.

Hi,
Hi here i have a dataframe called MyDF.
a-c(1,1,1,1,1,0,0,0,1,1)
b-c(1,1,0,1,1,0,0,0,1,1)
c-c(1,1,1,1,1,1,1,0,1,1)
d-c(1,1,1,1,1,1,1,1,0,1)
MyDF-data.frame(DWATT=a,TNH=b,CSGV=c,BIX=d)
My requirement is, here i need a function - to get for a
particular row number(s), when particular column(s) value change from
one-to-zero (for the first change). Suppose there is no change is
happening then it should return Zero
For example, Using MyDF,
DWATT TNH CSGV BIX
1 11 1
1 11 1
1 01 1
1 11 1
1 11 1
0 01 1
0 01 1
0 00 1
1 11 0
1 11 1
Here i want to know, the row number where TNH-column and BIX-column values
change happening from one-to-zero for the first time.
Note:- Suppose there is no change is happening then it should return Zero
Answer should be a dataframe with single row.
So here answer should return a dataframe like this.
TNH BIX

3 9
i used some ways to get a solution using loops. But there is a bulk files with
bulk rows to process.
So performace is most important. Could someone please suggest better ideas ?
Thanks,
Antony.
