Hi Everyone,
Sorry for coming back again with a new problem.
Editing question, session info and data so you don't have to scroll till
the end of page.
*Situation :*
I have a data frame and it's name is df. Now I want to add Time Stamp to
the end of *"name" of "data Frame" i.e. "df_system_time"*. Previously it
was running great and thanks to Dr. Winsemius , Kimmo and Pascal and I
believe as the function which i used was scalar.
*Data :*
dput(df)structure(list(x = 1:10, y = 1:10), .Names = c("x", "y"),
row.names = c(NA,
-10L), class = "data.frame")
*Session Info :*
R version 2.15.1 (2012-06-22)
Platform: i386-pc-mingw32/i386 (32-bit)
locale:
[1] LC_COLLATE=English_United States.1252
[2] LC_CTYPE=English_United States.1252
[3] LC_MONETARY=English_United States.1252
[4] LC_NUMERIC=C
[5] LC_TIME=English_United States.1252
attached base packages:
[1] stats graphics grDevices datasets utils methods
[7] base
other attached packages:
[1] rcom_2.2-5 rscproxy_2.0-5
loaded via a namespace (and not attached):
[1] colorspace_1.1-1 dichromat_1.2-4 digest_0.5.2
[4] ggplot2_0.9.2.1 grid_2.15.1 gtable_0.1.1
[7] labeling_0.1 MASS_7.3-18 memoise_0.1
[10] munsell_0.3 plyr_1.7.1 proto_0.3-9.2
[13] RColorBrewer_1.0-5 reshape2_1.2.1 scales_0.2.2
[16] stringr_0.6.1 tools_2.15.1
It's kind of very easy in SQL but I love doing all the work in R so don't
want to leave for just changing the name.

Bhupendrasinh Thakre
