R help - Jan 2014 - extracting rows from data frame that approximately equal another data frame

Hi,

May be this helps:
x <- data.frame(V1=-1.162877, V2=0.1848928)
?set.seed(245)
df <- as.data.frame(matrix(rnorm(5051*2),ncol=2))

?cut1 <- cut(df[,1],breaks=c(x[,1]-0.1,x[,1]+0.1))
?cut2 <- cut(df[,2],breaks=c(x[,2]-0.1,x[,2]+0.1))

df1 <- df[!is.na(cut1) & !is.na(cut2),]

A.K.



I have a dataframe and would like to extract rows that approximately?equal to
the values in another data frame.

say I have a data frame called x 

dim(x) 
[1] 1 2 


x 
? ? ? ? ? V1 ? ? ? ?V2 
x -1.162877 0.1848928 


I would like to search through a larger data frame 
called df and extract all rows that approximately equal the two values 
in the data frame x by say +- 0.1. 

The larger dataframe has these dimensions 

dim(df) 
[1] 5051 ? ?2
