Hello all!
I want to create a new variable in a dataframe, and this variable is based
on a regression equation. For example for example for the hc<=10, the
values of the new variable(d0.3) is obtained by d0.3=15.9122+0.2105*dc, for
hc<=30, d0,3 values are obtained by d0.3=1.4781+0.8827*dc.
Thank y

Hi:
I have asked this question on Cross-Validated. So it might be a cross
posting but havent received any responses to it.
I am trying to see which distribution will best fit the data I am working
on. The dataset is as following:

HI,
Try:
library(plyr)
res1<-ddply(df2aggregate,.(id),summarize,x=sum(x),y=mean(y),a=head(a,1))
res1
# id x y a
#1 a 3 NA
#2 b 7 2.5 A
#3 c 11 4.5 C
#4 d NA NA E
res1$x<- as.numeric(res1$x)
identical(ag1.2,res1)
#[1] TRUE

Hi,
You can do:
vec1<-scan(text="[1] 18 18 17 14 17 13 13 18 13 16 16 14
[1] 12 19 15 21 13 17 10 13 18 14 17 13
[2] 13 15 20 14 18 15 10 12 20 17 17 17",what="character")
as.numeric(vec1[-grep("\\[",vec1)])
# [1] 18 18 17 14 17 13 13 18 13 16 16 14 12 19 15 21 13 17 10 13 18 14 17 13 13

Dear R-user,

Hello:
Do you have suggestions for how to aggregate a data.frame using
different functions on different columns?
Consider the following example:
df2aggregate <- data.frame(id=rep(letters[1:4], each=2),
x =c(1:6, NA, NA),

Hi,
According to the error, the variables should have the same length.
For example:
set.seed(24)
dat1<-
cbind(RACE=sample(1:10,10,replace=TRUE),as.data.frame(matrix(sample(1:100,20*10,replace=TRUE),ncol=20)))
lapply(dat1[,-1],function(x)
