Replace a variable by its value
I have a dataset called "raw-data" . I am trying to use the following code -
col_name<-names(raw_data)
for (i in 1:(length(names(raw_data))-2))
{
tbl=table(raw_data$Pay.Late.Dummy, raw_data$col_name[i])
chisqtest<-chisq.test(tbl)
}
Say the 1st column of my raw_data is Column1. The idea is when i=1 then
raw_data$col_name[i] will automatically become raw_data$Column1 , which is
not happen...

how to skip a numeric column for averaging other columns?
Data has the first row for variable name and the first column for sample
name. I want to take "Log" for all data, but how to compute without the
first column for sample name.
That is,
column 1: sample ID
column 2-10: data
I want to find an average on each column (2-10)
> apply(raw_data,2,mean)
Error in Math.data.frame(list(sample_id = c(1L, 2L, 3L, 4L, 5L, 6L, 7L, :
non-numeric variable in data frame: sample_id
Thank you in advance,
Jin

Singular design matrix in rq
...ggers:
I'm trying to run rq() on a dataset I posted at:
https://docs.google.com/file/d/0B8Kij67bij_ASUpfcmJ4LTFEUUk/edit?usp=sharing
(it's a 1500kb csv file named "singular.csv") and am getting the following
error:
mydata <- read.csv("singular.csv")
fit_spl <- rq(raw_data[,1] ~ bs(raw_data[,i],df=15),tau=1)
> Error in rq.fit.br(x, y, tau = tau, ...) : Singular design matrix
Any ideas what might be causing this or, more importantly, suggestions for
how to solve this? I'm just trying to fit a smoothed hull to the top of
the data cloud (hence the large df).

Powercom driver patch
...com users on the official support forum (
http://forum.pcm.ru ).
I suppose the problem concerns models with serial-over-usb connection
implemented via cypress_m8 chip (ID 0d9f:0002), e.g. IMD-865AP USB,
BNT-1000AP USB, etc. (these are on sale everywhere in Russia). The
thing is that such UPS sends raw_data[UPSVERSION]==0xFF like
"Imperial" series and simultaneously raw_data[MODELNAME]==0x4B like
"KING" series (the explanation is proposed here -

barplot that displays sums of values of 2 y colums grouped by different variables
...g plot should have city as the x-axis, 2 bars per city, 1
representing the sum of "n" in that city, the other the sum of "y" in
that city.
If possible also show the sum in each bar as a label?
I aggregated the data into sums like this:
sum_data <- aggregate(. ~ City,data=raw_data,sum)
this gave me the sums per city as I wanted but for some reason 1 of the
cities is missing in the output.
Using this code for the plot:
ggplot(sum_data,aes(x = City,y = n)) + geom_bar(aes(fill = y),stat =
"identity",position = "dodge")

plot two time series with different length and different starting point in one figure.
Hello,
I do have two different time series A and B, they are different in length and starting point. A starts in Jan, 2012 and ends in Dec, 2012 and B starts in March, 2012 and ends in Nov, 2012.
How can I plot those two series A and B in the same plot? I.E., from Jan. 2012 - Feb, 2012, it would have one data point from A and from Mar, 2012-Nov, 2012, it would have two data points from A and B,

NA in last row while reading xlsx file
Hi,
I am using this script to read a xlsx file to a data frame:
library(xlsx)
File <- file.path("d:", "car ", "car95-99.xlsx")
B_car <- read.xlsx(File, "raw_data")
Car2x <- data.frame(month = B_car$Date,Ch = B_car$Ch.des,
lat=B_car$Latitude)
The last row in the data.frame is always NA, how can I remove it?
Thx.
