Hi R-helpers, I want to determine the coefficients of the following regression for several subsets, and I want to save it in a dataframe: The data is in ?regaccdis?, ?regaccdis$caedois? is the column that defines the subsets and the function I have runned is coef(plm(ff,data=regaccdis,na.action=na.omit,model="pooling",subset=(regaccdis$caedois==i))) I?ve created a dataframe named ?coef? to store the coefficients like this : caedois b1 b2...

Hi R-helpers! I have the following object: > head(coeficientes) caedois b1 b2 b3 1 1 0,033120395 -20,29478338 -0,274638864 2 2 -0,040629634 74,54239889 -0,069958424 3 5 -0,001116816 35,2398622 0,214327185 4 10 0,171875 5 14 0,007288399 40,06560548 -0,081828338 6 15 0,027530346 0,969969...

Thank you all!!! The problem was the decimal symbol! My data was saved in a txt file, so I?ve introduced the dec="," in ?read.table? and it worked. What I?ve done was coeficientes<-read.table("coeficientes.txt",sep="\t",header=T,dec=",") Then, subset worked fine coeficientesWanted<-subset(coeficientes,b1>0) Thanks again, Cec?lia Carmo
