Hello Everyone,
I have written certain codes in RShiny app which works fine.
There are 3 tabs, "Z1", "Z2" and "Z3". Currently the sliderinput shows up
when I click all the 3 tabs.
I need to adjust this code so that sliderInput is only visible when i

Hello Everyone,
I have written a loop which reads hundreds of .nc files
and extract information from each .nc file and

The loop works fine until it encounters a .nc file which it cannot read

Hi Bhaskar,
You can put all sorts of stuff into a text file simply by using the
"sink" command:
sink("bm.txt")
cat("\n")
B9<-"B"
cat(B9,"\n",sep="")
for(i in 1:9) cat("C")
cat("\n")
print(df)
sink()
What you intend to do with a file like this is beyond me.

You appear to either be ignorant of the structure pf data frames or
have not expressed yourself clearly enough (for me, anyway). Please go
through a tutorial to learn about the fixed structure of data frames,
for which your request does not appear to reflect an understanding.

Hello Everyone,
I have a data frame which looks something like this:
V1 <-c(1,2,3)
V2 <-c(5,6,7)
V3 <-c(9,10,11)
df <- data.frame(V1,V2,V3)
I want to add couple of text files at the beginning of df and save
the df as a csv file.
The csv file should look something like this:

You do not say whether the problem is (a) creating a help page to start
with (b) understanding how to edit it afterwards. If the former then
Duncan's advice to use prompt (or package.skeleton if you have not got
anything set up yet) is good advice. If (b) then try it and post agai
