Have you used RGoogleDocs and RGoogleData?
Both of these applications fulfill a great need of mine: to read data
directly from google spreadsheets that are private to myself and one or two
collaborators. Thanks to the authors. I had been using RGoogleDocs for the
about 6 months (maybe more) but have had to stop using it in the past month
since for some reason that I do not understand it no longer reads google
spreadsheets. I loved it. Its

Extract confidence intervals from rma object (metafor package)
Dear R-experts!
I am working on some meta-analysis using the metafor package. I would like
to extract values of the confidence intervals of the effect sizes of the
single studies from an rma object. Those values are printed out when
plotting a forest plot using the forest function on the rma object, however
I was not able to locate them.
Many thanks for your help!

Using dcast with multiple functions to aggregate
Dear R communitiy,
I am trying to use multiple functions for aggregation within a function
call for dcast. However this seems to result in an error. Also I have not
managed to make dcast() work with fun.aggregate=sd. Please find attached
some example code using the ChickWeight data.
Many thanks for your help!

Power calculation using pwr.t.test()
Dear R experts,
I have conducted a power calculation in order to estimate the number of
subjects needed to detect an effect size of d=0.28 (cohen's d) for a
difference between two independent groups (alpha level should be 0.05 and
the effect should be detected with 80% probability).
The results from the code below indicates that I would need n=400 subjects
(200 in each group). This is seems

Estimate average standard deviation of mean of two dependent groups
Dear R-experts!
I am currently running a meta-analysis with the help of the great metafor
package. However I have some difficulties setting up my raw data to enter it
to the meta-analysis models.
I have a group of subjects that have been measured in two continuous
variables (A & B). I have the information about the mean of the two
variables, the group size (n) and the standard deviations of

Would a spreadsheet be a good project using LLVM?
I am thinking about writing a new open source spreadsheet
application since I think the spreadsheet applications out
there (Microsoft Excel, LibreOffice Calc, etc.) do not have
some features that I would really like to use. I would like
the spreadsheet to recalculate very fast and wondered if it
would make sense to use LLVM to calculate the cell values
quickly. Each cell of a spreadsheet

Would a spreadsheet be a good project using LLVM?
Mats,
Thanks for your feedback. I guess I should elaborate on one
of the features I would like to implement. In today's
spreadsheets if you want to crunch a lot of data, you
usually put the data in rows and put expressions in cells to
the right of the data and repeat those cells for every row
of the data. I would like to create a spreadsheet system
that can process the same quantity of

Converting F-value from ANOVA to cohen's d in meta-analysis (metafor-package)
Dear R-experts!
Running a meta-analysis (using the magnificent metafor-package), I use
cohen's d as a main outcome measure in a random-effects model.
For most of the samples cohen's d is derived form a comparison of two groups
(A & B). However some studies report results from an ANOVA (one-factor with
three levels: C,D,E) whereas two groups (C,D) correspond to one group in the
other

Main-effect of categorical variables in meta-analysis (metafor)
Dear R-experts!
In a meta-analysis (metafor) I would like to assess the effect of two
categorical covariates (A & B) whereas they both have 4 levels.
Is my understanding correct that this would require to dummy-code (0,1) each
level of each covariate (A & B)?
However I am interested in the main-effects and the interaction of these two
covariates and the dummy-coding would only allow to

Getting value rather than formula in RGoogleDocs
Is there an easy way to read the value of the cells rather than the formula?So
for instance in a cell whose value was created by simply using the value
from the cell immediately to the left in the Google spreadsheet I would
prefer to get the value rather than =RC[-1]
When one exports with Google Spreadsheets as a csv then that does not
happen.
I am using the following line of code in R

Annotate forest plot 'forest.rma()' for meta-analysis with metafor package
Dear R-experts,
The forest.rma() function from the metafor package creates nice forest
plots for presenting the results of a meta-analysis. These plots can be
annotated for e.g. giving names to the columns. E.g. as in the
documentation of the package:
data(dat.bcg)
### meta-analysis of the log relative risks using a random-effects model

RODBC: problem saving a new table in an "Excel database"
Hi
I am using package RODBC version 1.0-1 under R version 1.7.1 on Windows
XP Pro. I am having problems writing a new table to an (Excel) database
using sqlSave.
I connect to an empty Excel spreadsheet using odbcConnectExcel (which, I
believe, uses the Microsoft Excel Driver DSN). Then I try and save a new
table to the database(spreadsheet) using SqlSave, but obtain an error

RGoogleDocs not working for me with "wise" service
Hello,
I'm trying to figure out how to use the RGoogleDocs package from OmegaHat,
and am having a bit of trouble. I emailed Duncan Temple Lang directly, but
didn't receive a response, so I thought I'd try here to see if anyone else
can help.
I'm using 32-bit R 2.10.1 (Mac OS X), I built RGoogleDocs 0.4-0 from source,
and I'm using XML 3.1-0 and RCurl 1.2-0.

importing data from Excel using RODBC
Hi,
I used RODBC to import data from an Excel spreadsheet "*.xls", but some
columns were returned as zeros. When I looked at these columns in Excel, I
found that thery are results of formula calculations and not entry. My
question is: Is there any parameter or command I need to use in order to
overcome this problem?
Thank you

Excel
A common process when data is obtained in an Excel spreadsheet is to save
the spreadsheet as a .csv file then read it into R. Experienced users
might have learned to be wary of dates (as I have) but possibly have not
experienced what just happened to me. I thought I might just share it with
r-help as a cautionary tale.
