Dear Statalist members,
I have a dataset that I will have to reshape but I am facing two
challenges for now. My dataset is currently organized as follows:
The first column (var1) contains different dates.
The next columns (var2-var1285) contains my variable of interest.
However, the first line contains the identifier of the firm and then
the value of the variable of interest.
My first problem is that some identifiers are not valid, and then the
first line returns an error message (string format). I want to drop
all columns with an error message. I have tried the following code:
forvalues i=2(1)1285{
drop var`i' if var`i'[1]=="#ERROR"
}
However, it returns the following message: "invalid syntax".
My second problem is that the valid identifiers are of the following
form, 6 figures ending by (PE):
example : 123456(PE)
I need to eliminate the (PE) at the end of each identifier. I have
tried to use the regex command but it did not worked well.
I welcome any idea !
Thanks in advance
Best
Thomas
