Hi everyone,
I am translating an R code into a Julia code, I have this function in R :
> for (i in 1:length(l)) {
> if(length(l[[i]])\>0){
> a ← l[[i]]
> y[i,a+c-1] ← as.numeric(
> gsub(“,”,“”, work.matrix[which(row.names(work.matrix)==i),colnames(work.matrix)%in% a], fixed = TRUE))
> }
> }
I translated it like that in Julia :
> for key in keys(l)
> if length(l[key]) \> 0
> a = l[key]
> b = rownames .== key
> d = [i for i in a]
> y[key,(a .+ c .- 1)] = replace.(work\_matrix[b,d],“,” =\>“”)
> end
> end
But I get this error : no method matching similar(::Int64, ::Type{Any}), does anyone know why ? Thank you !

Hi. I don’t know exactly what the problem is, but you can make it easier to understand if you provide more input. I suggest that you read this post: [Please read: make it easier to help you](https://discourse.julialang.org/t/please-read-make-it-easier-to-help-you/14757), which gives some tips on how to write questions that are clearer to the reader.
In particular, tip number 4 in that post is relevant. When we cannot tell what sort of data you are working on, it is difficult to understand what is going wrong.
