Hello,
I am trying to run a fixed effects panel regression on data containing 5
columns and 1,494 rows.
I read the data in as follows:
>drugsXX<-read.csv(file="C:\\Folder\\vX.X\\Drugs\\drugsXX_panel.csv",
head=TRUE, sep=",")
Verified it read in correctly and had a good data.frame:
>dim(drugsXX)
[1] 1494 5
>drugs XX
produce expected data with correct column names
The issue is, when I go to run the plm using:
>fixed <- plm (h ~ o + m + a, data=drugsXX, index=c("h","year"),
model="within")
I get this error:
Error in names(y) <- namesy :
'names' attribute [996] must be the same length as the vector [0]
I know the data recognizes that I have 5 columns. I also know that there's
nothing wrong with row 996 (I even want back and checked for hidden
characters in the original .csv file).
traceback() was useless:
4: pmodel.response.pFormula(formula, data, model = model, effect = effect,
theta = theta)
3: pmodel.response(formula, data, model = model, effect = effect,
theta = theta)
2: plm.fit(formula, data, model, effect, random.method, inst.method)
1: plm(h ~ o + m + a, data = drugsXX, index = c("h",
"year"), model = "within")
What explicit steps can I follow to get my panel regression to run?
Thank you,
Laura
