Answer 1

We can unlist the dataframe and convert it into the matrix of nrow/2 rows

data.frame(matrix(unlist(df), nrow = nrow(df)/2, byrow = T))

#   X1    X2
#1  2 0.002
#2 52 0.060
#3 61 0.090
#4 70 0.120
#5 85 0.920

Answer 2

We can do a logical index and create two columns

i1 <- c(TRUE, FALSE)
df2 <- data.frame(col1 = df1$beta[i1], col2 = df1$beta[!i1])
