level sets of factors are different
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??

ccf function
Hello,
I am a very new R user and not a statistician so please excuse any over
explanation, I'm just trying to be as clear as possible.
I have performed a cross correlation of two time series (my columns) in a single
data setusing:
ccf(ts(A[rows,columnX]),(A[rows,columnY]), lag=NULL, type="correlation",plot=F)
I?am able to get the results (for example):
Autocorrelations of series ?X?, by lag
?? -14??? -13??? -12??? -11??? -10???? -9???? -8???? -7???? -6???? -5???? -4
-0.128 -0.126 -0.109 -0.087 -0.060 -0.035 -0.002? 0.027? 0.064? 0.1...
