Hi, I have two data frames A en B. I want to filter B with values of A data_frame_b names <- colnames(data_frame_b[1:1, ]) filtera <- data.frame(data_frame_a[1:1]) print(nrow(filtera)) if (nrow(filtera)>0){ filtered_frame_b <- subset(data_frame_b, ColumnX == filtera[1, 1], names) } The results are: [1] 124 Error in Ops.factor(ColumnX, filtera[1, 1]) : level sets of factors are different What is wrong??
