Dear Users,
Is there way to avoid the useless title (Rattle, date-time and user
imformation) at the bottom of the fancyRpartPlot. We already referencing it why
should it be there?
Thanks,

Thanks Michael.
I have read the original article and I guess whether the following formula

*for trend, *

Dear R forum
I have following variables -
EAD = 1
LGD = 0.45
PD = 0.47
M = 3
# Equation 1
R = 0.12*(1-exp(-50*PD))/(1-exp(-50)) + 0.24*(1-(1-exp(-50*PD))/(1-exp(-50)))
b = (0.11852 - 0.05478 * log(PD))^2
K = (LGD * pnorm((1 - R)^(-0.5) * qnorm(PD) + (R / (1 - R))^0.5 * qnorm(0.999))

Dear All,
I am bit stuck to a problem of replacing to NA.
I have big data set but here is the toy example:-
test-data.frame(
test1=c(,Hi,Hello),
test2=c(Hi,,Bye),
test3=c(Hello,,))
If the data as in above, I could change all to NA by this code:-
for(i in 1:3){
for(j in 1:3){
if(test[j,i]==){

I tried to install R on my laptop which has Office 2013 on it. The
download didn't work, is this because R is not compatible with Office

Thanks

Hi
Reading the error message carefully you can see that f() is not defined at 0:
uniroot(f, c(0, 1))
Error in uniroot(f, c(0, 1)) : f.lower = f(lower) is NA
f(0)
[1] NaN
If you plot f() in the interval (0,1) then you'll see there is two solutions:
uniroot(f, c(0.0001, 1))

In a word, no. It's more likely that some corporate security barrier
is preventing installation.

can you be more specific? In what aspect those packages does not comply with

I am not an expert in neural networks but I do not see anything which prevents
using your data in nnet.

Hi Arun Jim Marc,
Thank you!
The solution worked well!
It seems I am using too many unnecessary loops to solve my problems. I
have tried using is.na() before posting:
for(i in 1:3){
for(j in 1:3){
if(is.na(test[j,i])){
test[j,i]=
}
}
} # but here the factors were creating problems.
Thanks

Colleagues,
I know little about encoding so please be patient with this question. I have a
CSV file created from a SAS7BDAT dataset (using Shotwell's SAS7BDAT package).
In the CSV file, when opened with XL, one entry reads as:

When I read this into R, that

ts1 - ts(rnorm(2*blockLength-1, 0,2), frequency=blockLength)
de - decompose(ts1) # error

de - decompose(ts2)

So the trick is to have at least two periods in your time series. Even
For decomposing a time series into seasonal components, you need at least 2
seasons worth of data. If you have even one data point less, you will see
this error message.

You could compare the outputs of
z1 - with(dd, dd$EVYEAR==2012 dd$EVMONTH=='02')
(which is like subset()) and that of
z2 - dd$EVYEAR==2012 dd$EVMONTH=='02'
(evaluated from within the same context) with
table(z1, z2, exclude=NULL)
That may show something useful.

There is no unused space. It is very hard to see how you could remove
the empty space and still have a meaningful graph.
