Hello Ulrik,
Can you please explain this code means how and what this code is doing
because I'm not able to understand it, if you can explain it i can use it
in future by doing some Lil bit manipulation.
Thanks

mutate(Purchase_ID = 1:n()) %>%
group_by(Purchase_ID) %>%

by using these two tables we have to create third table in this format
where categories will be on the top and transaction will be in the rows,

Hi Hemant,
the solution is really quite similar, and the logic is identical:
library(readr)
library(dplyr)
library(stringr)
library(tidyr)
data_help <- read_csv("data_help.csv")
cat_help <- read_csv("cat_help.csv")
# Helper function to split the Items and create a data_frame
split_items <- function(items){
x <- items$Items_purchased_on_Receipts %>%

dear group,
i have 100 files starting with 'hsa-*'.
ex. file:
fruit p-value
------------
apple 0.0003
orange 0.004
kiwi 0.0003
peach 0.0004
I want to read all these files and create a single
matrix. here each file may have different fruit names.
in the matrix i want to have a union of all fruits and
those should be the rows in the matrix and file names
should be columns.

Hi
It seems to me like homework, there is no homework policy on this help list.
What do you want to do with your table 3? It seems to me futile.
Anyway, some combination of melt, merge, cast and regular expressions could be employed in such task, but it could be rather tricky.
But be aware that
Suger does not match sugar (I wonder that sugar is dairy product)

ubuntu equivalent of ctrl-a on windows
Hi All: I'm using an old version of Ubuntu, 14.04, and I can't figure out a
keyboard sequence that "selects all" analogously to what ctrl-a does on
windows ?
If anyone can be bothered running below and see if they have a way to
select all four fruits at once, it's appreciated. I've spent quite a bit of
time searching the net, going on AskUbuntu etc
but no luck. Thanks.

Dropdown boxes in tcltk and R
Hello,
I'm very much a newbie in R and more so in tcltk so apologies if this
question is stupid. Basically I am trying to use the combobox example
found here:

What I want to do is in that example get fruitChoice as a variable in R
in general. When I run that code, however, and the ask for fruitChoice

assign factor levels based on list
All,
Given a data frame and a list containing factor definitions for certain columns, how can I apply those definitions from the list, rather than doing it the standard way, as noted below. I'm lost in the world of do.call, assign, paste, and can't find my way through. For example:
#set up df
y <- data.frame(colOne = c(1,2,3), colTwo =

Return all rows, split then show uniques
I''m returning some rows from a tags database that look like this:

What I want to do with that data is use the .split method to divide them

unique list of the words like so:

How to spec a (Trollop-based) binary’s internal state?
I?m trying to spec a ?binary?, and as previously discussed on this list,
I?m trying to do it ?from outside? ? i.e., by calling it with Kernel#`
and observing the (side-)effects.
Unfortunately, this doesn?t really let me spec expectations about its
internals. Let?s assume I have a -d flag and I parse it with Trollop to
set Conf.debug:
opts = Trollop::options do

splitting dataframe, assign to new dataframe, add new rows to new dataframe
Hi, all,
My objective is to split a dataframe named "cmbine" according to the value of "classes". After the split, I will take the first instance from each class and bin them into a new dataframe, "df1". In the 2nd iteration, I will take the 2nd available instance and bin them into another new dataframe, "df2".
