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))

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...
