Can you explain the setup further -- Where is the REPL running? How are you interacting with it? If I take "I want to temporarily switch the REPL off, i.e. it should visually disappear" literally then it seems like a strange thing to do, so I may be missing something If you *do* want to hide the t

Re: [julia-users] Question: Forcing readtable to create string type on import

Unless I misunderstand, df1 = readtable(file1,eltypes=[String,String,String]) seems to be what you want. If you're new to Julia, the fact that a "vector of types" really means exactly that may be surprising. Let us hope that the new versions of DataFrames include a parser that doesn't treat

LeAnthony, I'm wondering if you're on an old version of DataFrames? There haven't been any issues "show"-ing DataFrames with NullableArray columns for quite some time. You can check (and post back here) your current package versions by doing: Pkg.installed() You can also ensure you're on the lat

Thanks Michael, I been thinking about this all day. Yes, basically I am going to have to create a macro *CSVreadtable* that mimics the *readtable* command, but in the expantion uses *CSV.read*. The macro will manually constructs a similar readtable sized dataframe array, but use the column t

Re: [julia-users] Question: Forcing readtable to create string type on import

DataFrames is currently undergoing a very major change. Looks like CSV creates the new type of DataFrames. I hope someone can help you with using that. As a workaround, on the normal DataFrames version, I have generally just replaced with a string representation: ``` df[:account_numbers] = ["$accou

Re: [julia-users] create command with spaces without quoting

Interpolating commands into commands is a useful pattern as well: cmd = `convert` if haskey(opts, :density) cmd = `$cmd -density $(opts[:density])` end if haskey(opts, :depth) cmd = `$cmd -depth $(opts[:depth])` end run(cmd) On Thu, Nov 3, 2016 at 12:21 PM, Yichao Yu wrote: > On Thu,

Re: [julia-users] what is "type piracy"?

As far as I know "type piracy" is not a widespread term in CS, but has popped up in the Julia community. Basically it refers to violations of the Julia guideline that a package shouldn't define methods of functions it doesn't own on types it doesn't own. For example, if package A exports a functi

I want to generate a command for imagemagick and use options loaded from a file. So the number of utilized options is not known beforehand. An example might look like: convert -density 300 somefile.pdf -depth 10 somefile.jpeg It is easy to generate the string above, but when interpolating it in

[julia-users] what is "type piracy"?

What does the term "type piracy" mean? The term shows up in julia-related discussions, mostly on Github. Googling for it leads back these discussions, and a lot of unrelated stuff about copyright and/or typefaces. (Apologies if the term is well-known, I am an economist, not a computer scientist).

Sure, so I need col #1 in my CSV to be a string in my data frame. So as a test I tried to load the file 3 different ways: *df1_CSV = CSV.read("$df1_path"; types=Dict(1=>String)) #forcing the column to stay a string* *df1_readtable = readtable("$df1_path") #Do not know how to force the col

Sure. It's just taking all the changes that have been made and stashing them to one side. This means the Git repository is then "clean" and can be updated. Git stash apply takes the changes that had been stashed and reapplies them to the updated repository. Bill. On 2 November 2016 at 22:01, digx

Jeffrey, Thanks, but my question was about how to have line and column in the error message. So I would like to have an error message like this: ERROR: Failed to parse "error" as type Int64 in column 2, line 3. My best idea so far: catch the error at each level, and add i and line number. But th
