Dear R-helpers,
I hope someone can help me with the following problem:
I derived a variable from many others and produced data.frame: toktempo
When I look at the variable name I get:
names(toktempo)
[1] "otok.V5"
But I want the variable name to be Tempo so I googled around to find info
about renaming variables.
I found a webpage which seemed to indicate to me that there was a package
named gmisc which contained a function called rename and it's syntax looked
like
what I wanted. Another webpage indicated that gmisc is a bundle and there are
four packages: gtools, gdata, gmodels, and gplots. I think gdata might have
the rename function. So I did:
chooseCRANmirror()
install.packages(c("gdata"))
After this, library() shows that I now have gdata:
Packages in library 'C:/PROGRA~1/R/R-23~1.0/library':
base The R Base Package
boot Bootstrap R (S-Plus) Functions (Canty)
class Functions for Classification
cluster Cluster Analysis Extended Rousseeuw et al.
datasets The R Datasets Package
foreign Read Data Stored by Minitab, S, SAS, SPSS,
Stata, Systat, dBase, ...
gdata Various R programming tools for data
manipulation
graphics The R Graphics Package
grDevices The R Graphics Devices and Support for Colours
and Fonts
grid The Grid Graphics Package
KernSmooth Functions for kernel smoothing for Wand & Jones
(1995)
lattice Lattice Graphics
MASS Main Package of Venables and Ripley's MASS
methods Formal Methods and Classes
mgcv GAMs with GCV smoothness estimation and GAMMs
by REML/PQL
nlme Linear and nonlinear mixed effects models
nnet Feed-forward Neural Networks and Multinomial
Log-Linear Models
But when I do library(gdata) I get:
Error in loadNamespace(i[[1]], c(lib.loc, .libPaths())) :
there is no package called 'gtools'
In addition: Warning message:
package 'gdata' was built under R version 2.3.1
Error: package/namespace load failed for 'gdata'
And when I do help(rename) I get:
help(rename)
No documentation for 'rename' in specified packages and libraries:
you could try 'help.search("rename")'
Of course I don't really know if gdata includes something called rename but
I'm most hoping the message from library(gdata) will mean something to
someone.
Or maybe someone has other ideas to help me with my renaming problem.
Many thanks,
Tom Brotz

I'd update to 2.6.0 (or wait a couple of weeks and update to 2.6.1). In that version, install.packages("gdata") would have installed the necessary dependencies. I think you can get similar behaviour in your version by install.packages("gdata", dependencies=TRUE) However, the current version of gdata requires R 2.4.0 or better, so you'll be installing an obsolete version of the package, too.

The Hmisc package's upData function makes it easy to rename variables, and at the same time you can provide labels, value labels (factor levels), units of measurement, and other things.
