I tried using RHEOS to import a csv file which has two columns with data, the first being time and the second being stress. I followed the documentation of RHEOS:

# Import file

data\_1 = importcsv(“assets/data\_time.csv”, t\_col = 1, ϵ\_col = 2, σ\_col = 3)

# Check data type

rheotimedatatype(data\_1)

and used:

julia\> using RHEOS

julia\> data\_1 = importcsv(“tryout.csv”, t\_col = 1, σ\_col = 2)  
ERROR: MethodError: no method matching nanremove(::Matrix{Any})

Closest candidates are:  
nanremove(::Matrix{T}) where T\<:Real  
@ RHEOS C:\Users\maruja.julia\packages\RHEOS\4cxTK\src\IO.jl:9

Stacktrace:  
[1] importcsv(filepath::String; delimiter::Char, header::Bool, comment::String, savelog::Bool, kwargs::Base.Pairs{Symbol, Int64, Tuple{Symbol, Symbol}, NamedTuple{(:t\_col, :σ\_col), Tuple{Int64, Int64}}})

I don’t know what this error means and I couldn’t find anything on it. I am very new to programming so any help is appreciated
