It shouldn't print all the rows and columns as default about dataframe-go HOT 9 CLOSED

I'll eventually fix it up so it displays the first 3 and last 3 rows.
Alternatively, you can provide a PR and replicate the String() function in the Series structs.

I am not a programmer and I am just learning Golang but I will try to help you out if possible. If there is something easy you want me to do I will surely do it.

I think this library needs

1. Import from SQL
2. Import from excel
3. select columns
4. Filter Rows
5. Group By Values
6. Basic functions like sum, mean etc....

Let me know if I can help in any of these. Best of Luck!!!

1. 2. I won't have time to implement import from SQL or Excel any time soon. That will require assistance from others.

3. What do you mean Select columns?
The function NameToColumn(seriesName string) combined with the Series field can be used to select columns.

4. 5. These I will work on when I figure out the best API to do so.

6. This is doable.

I think these sounds like great ideas!

1. and 2. could be part of a longer term project road map.
4., 5., and 6. sound like great shorter term features to tackle.

can I help out anywhere @rocketlaunchr-cto ? we will have to break up large goals into manageable pieces..

@bk521234 How would you like to help. I can write up a document on what you can do.

from dataframe-go.

i'd be willing to chip in some help to add a few features. a document could be really useful. maybe a wiki page with stuff? or small-ish projects for the near term?

I think the more functionality the package has, the more willing people will be to adopt/ use it

from dataframe-go.

I am not a good programmer but I can help too. But If I get stuck somewhere I would want you to help me too... Start a slack channel or something where we could work.

@vikram-rawat @bk521234 Here are some tasks:

1. For func (df *DataFrame) NRows() int, insert an optional bool parameter so enable/disable the read lock inside the function. The default should be to read lock.

2. Fix up the func (df *DataFrame) String() string { function found in dataframe_fmt.go to show only the first 3 items, then ..., then the last 3 items, similar to how the Series.String() function behaves.

They are easy changes.

This has now been fixed. Print will only show max 6 rows as summary.
