Anyone know of an R package that will allow me to do an inverse
Gaussian/Wald distribution transform of my data (reaction times)? Thanks!

Hi,
I have the following data about courses (504) in a university, two
attributes about the proportion of resources used (#resources_used /
#resources_available), namely the average and the standard deviation.
Thus I have:
[1] n=504 rows
[2] 1 id column and 2 attributes
Here's a sample of the
about R every day.

Hi,
Newbie here. I read the R for Beginners but i still don't get this.
I have the following data (this is just an example) in a CSV file:
courseid numstudents
101 209
141 13
246 140
263 8
321 10
361
) ... pretty
clearly a numeric value for which an ECDF should make sense.

Hi,
I want to do a visualisation of a matrix plot made up of several plots of
correlation matrices (using corrplot()). My data is in csv format. Here's an
example:
id,category,attribute1,attribute2,attribute3,attribute4
661,SCHS,43.2,0,56.5,1
12202,SCHS,161.7,5.7,155,16
1182,SCHS,21.4,0,29,0
Hi Petr,
It's not an equation. It's my mistake; the * are meant to be field
separators for the example data. I should have just use blank spaces as
follows:
users Group1 Group2 Group3
u110 5N/A
u2 6 N/A 4
u3 5 2
Thanks Petr. I will try it on the real data.
But that will only show that the groups are different or not.
Is there any way I can test if the users are different when they are in
different groups?
Regards
Gawesh

Hi,
I'm a newbie to R. My knowledge of statistics is mostly self-taught. My
problem is how to measure the effect of users in groups. I can calculate a
particular attribute for a user in a group. But my hypothesis is that the
user's attribute is not independent of each other and that the user's

going straight into the ditch with my solution please do let me know.

Jim's suggestion did the trick:
tqm - do.call(rbind, tq) + 0.001
head(x.new) userid freq track rating
[1,] 11
[2,] 1 u2 15 1
[3,] 1 u3 126 4
[4,] 1 u4 117 3
[5,] 1 u5 76 2

Hi Jim,
Thanks very much for the code. I modified it a bit because I needed to
allocate the track ratings by userid (eg if user 1 plays track x once

An easy way is to just offset the quantiles by a small increment so
that boundary condition is less likely. If you change the line
tqm - do.call(rbind, tq) + 0.001
in my example, that should do the trick.

Hi,
I have a mysql table with fields userid,track,frequency e.g
u1,1,10
u1,2,100
u1,3,110
u1,4,200
u1,5,120

where frequency is the number of times a music track is played by a
userid
I need to turn my 'frequency' table into a rating table (it's for a
recommender system).
