Adding labels on the scatterplot with R
I would like to label points on a scatterplot. I used the following code.

Code:
d1 <- structure(list(x1 = c(31.7858,25.8623,23.7758,30.1564,28.179,25.3966,31.5879,40.3233,28.8774,27.4434,37.6055,38.2847,40.5864,38.586,32.5489,38.2273,45.6876,52.3452,42.6654,49.8273), y1 = c(3.62,2.38,1.98,2.71,2.25,2.37,2.28,2.30,3.06,2.22,2.66,2.83,4.16,2.83,3.10,3.00,4.52,5.61,3.95,6.45)), .Names = c("x1", "y1"), class = "data.frame", row.names = c(NA, 
-20L))
d2 <- structure(list(x2 = c(22.5824,17.8283,21.4613,20.0485,24.5318,23.0919,23.3925,27.2867,23.7026,23.7338,25.4886,26.7058,25.6673,24.991,25.2346,18.7816,26.2372,25.9479,25.819,25.1697), y2 = c(2.12,1.55,1.65,1.52,1.80,1.77,1.68,1.46,2.05,1.63,1.59,1.85,2.53,1.98,2.32,1.66,2.09,2.51,2.25,2.54)), .Names = c("x2", "y2"), class = "data.frame", row.names = c(NA, -20L))
library(reshape2)
library(ggplot2)
names(d2) <- c("x1", "y2")
df <- rbind(melt(d1, id.vars = "x1"), melt(d2, id.vars = "x1"))
ggplot(df, aes(x1, y = value, colour = variable)) + 
  geom_point() + labs(x = "x", y = "y") +
  scale_colour_manual(values = c("red", "blue"), labels = c("d1", "d2"))

How can I label the points?

Code:
labels=c("L", "K", "D", "E", "N", "Q", "S", "G", "H", "W" , "A", "P", "Y", "V", "M", "C", "R", "F", "I", "T")

locale::codes::langfam5.18

Locale::Codes::LangFam(3pm)				 Perl Programmers Reference Guide			       Locale::Codes::LangFam(3pm)

NAME

       Locale::Codes::LangFam - standard codes for language extension identification

SYNOPSIS

	  use Locale::Codes::LangFam;

	  $lext = code2langfam('apa');		       # $lext gets 'Apache languages'
	  $code = langfam2code('Apache languages');    # $code gets 'apa'

	  @codes   = all_langfam_codes();
	  @names   = all_langfam_names();

DESCRIPTION

       The "Locale::Codes::LangFam" module provides access to standard codes used for identifying language families, such as those as defined in
       ISO 639-5.

       Most of the routines take an optional additional argument which specifies the code set to use. If not specified, the default ISO 639-5
       language family codes will be used.

SUPPORTED CODE SETS

       There are several different code sets you can use for identifying language families. A code set may be specified using either a name, or a
       constant that is automatically exported by this module.

       For example, the two are equivalent:

	  $lext = code2langfam('apa','alpha');
	  $lext = code2langfam('apa',LOCALE_LANGFAM_ALPHA);

       The codesets currently supported are:

       alpha
	   This is the set of three-letter (lowercase) codes from ISO 639-5 such as 'apa' for Apache languages.

	   This is the default code set.

ROUTINES

       code2langfam ( CODE [,CODESET] )
       langfam2code ( NAME [,CODESET] )
       langfam_code2code ( CODE ,CODESET ,CODESET2 )
       all_langfam_codes ( [CODESET] )
       all_langfam_names ( [CODESET] )
       Locale::Codes::LangFam::rename_langfam  ( CODE ,NEW_NAME [,CODESET] )
       Locale::Codes::LangFam::add_langfam  ( CODE ,NAME [,CODESET] )
       Locale::Codes::LangFam::delete_langfam  ( CODE [,CODESET] )
       Locale::Codes::LangFam::add_langfam_alias  ( NAME ,NEW_NAME )
       Locale::Codes::LangFam::delete_langfam_alias  ( NAME )
       Locale::Codes::LangFam::rename_langfam_code  ( CODE ,NEW_CODE [,CODESET] )
       Locale::Codes::LangFam::add_langfam_code_alias  ( CODE ,NEW_CODE [,CODESET] )
       Locale::Codes::LangFam::delete_langfam_code_alias  ( CODE [,CODESET] )
	   These routines are all documented in the Locale::Codes::API man page.
