Tidyverse/dplyr solution for filling values of a tibble/dataframe from a column with a nested list.
...0.1)
Basically, each list contains a set of doubles, with the first indicating a specific index (based on the 0 beginning python? index), and a certain value (e.g. 0.5).
What I would like to do is generate set of columns based on the rang of unique indexes of each nested list. e.g.:
col_1, col_2, col_3, col_4, col_5?
Which I have done with the following:
tibble[paste0("col_", 1:5)] <- 0
?And then replace each 0 with the value (second number in the nested list), based on the index (first number in each nested list), for each row of the tibble.
I wrote a function to split each neste...

Incluir símbolo matemático en data frame
Estimados miembros de la lista,
Cómo se puede incluir. por ejemplo, el símbolo de menor o igual en un
data.frame para luego hacer un cuadro (table con kable in rmarkadown)?
columna1 <- c("a", "b", "c")
columna2 <- c(<= 0.3, 0.5, 0.8)
columna3 <- c(>=0.5, 0.6, 0.9)
cuadro <- data.frame(columna1, columna2, columna3)
kable(cuadro)
