Hi,
I am working to understand the Rfast functions of colMins and colMaxs. I
worked through the example listed on page 54 of the PDF.
https://cran.r-project.org/web/packages/Rfast/index.html
https://cran.r-project.org/web/packages/Rfast/Rfast.pdf
My data is in a CSV file. So, I bring it into R Studio using:
Data <- read.csv("./input/DataSet05.csv", header=T)
However, I read the instructions listed on page 54 of the PDF saying I
need to bring data into R using a matrix. I think read.csv brings the
data in as a dataframe. I think colMins is failing because it is looking
for a matrix but finds a dataframe.
> colMaxs(Data)
Error in colMaxs(Data) :
Not compatible with requested type: [type=list; target=double].
> colMins(Data, na.rm = TRUE)
Error in colMins(Data, na.rm = TRUE) :
unused argument (na.rm = TRUE)
> colMins(Data, value = FALSE, parallel = FALSE)
Error in colMins(Data, value = FALSE, parallel = FALSE) :
Not compatible with requested type: [type=list; target=double].
QUESTION
What is the best practice to bring a csv file into R Studio so it can be
accessed by colMaxs and colMins, please?
Thanks,
