changing one character in the name of dataframes repeatedly
Dear R-community,
I'd like to ask you a question concerning R again. I try to keep this simple because I am not willing to confuse you at all.
I have a little data frame which I have created the following way:
a <-c(1,1,1,1,1,2,2,2,2,2,3,3,3,3,3,4,4,4,4,4,5,5,5,5,5,6,6,6,6,6)
b <-c(1,2,3,4,5,6,...

help - "the condition has length > 1 and only the first element will be used"
Hello there,
I don't know if I'm addressing my question to the right e-mail address, I hope I do. Actually I have a little problem concerning writing a code in R. I try to briefly sum up my problem.
As you can see below, I created the functions "Equation1" and "Equation2" with some conditions.
Equation1 <-function(x){
if (x<=0.25) y &l...

bootstrap resampling - simplified
Hello there,
I have a problem concerning bootstrapping in R - especially focusing on the resampling part of it. I try to sum it up in a simplified way so that I would not confuse anybody.
I have a small database consisting of 20 observations (basically numbers from 1 to 20, I mean: 1, 2, 3, 4, 5, ... 18, 19, 20).
I would like t...

quantile function -> I need only the quantile value itself
Hi,
I am using the quantile function currently and I have just bumped into a little problem.
I have a very small data frame something like this:
small_df <- c(7,3,4,7,1,10,12,1,12,4,4,8,6,11,9,10,4,13,3,9,6,5,2,10,7,14,2,7,10,10,7,8,2,11,3,10,11,3,11,14,12,7,6,11)
small_df
Now in the next step I would like to calculate the q...

deleting the first two characters in each row of a factorized column
Hello,
I'd like to ask you something again.
I have a database and it has a column which looks like this one here:
small_factor <- factor(c("d_variable1","d_variable2","d_variable3"))
small_factor
Now the thing is that I would like to convert each element of this factorized column. Basically I want to rewrite the words in it without the fir...

changing the dimensions of a matrix in a real specific way
Hi again,
I'd like to ask you a question again.
I have a matrix like this:
a <-matrix(c(1,2,3,4,5,6,7,8,9,10,11,12))
a
[,1]
[1,] 1
[2,] 2
[3,] 3
[4,] 4
[5,] 5
[6,] 6
[7,] 7
[8,] 8
[9,] 9
[10,] 10
[11,] 11
[12,] 12
Is there a proper way to change the dimensions of this matrix so that I'll get this as a result:
[,1] [,2] [,3]
[1...

recalling different data frames (the way you do in Excel VB)
Hello everyone,
I'd like to ask you a question again, basically focusing on referring to different objects.
Let's suppose we create the following databases this way:
id <-c(1,1,1,1,1,1,1,1,1,1,2,2,2,2,2,2,2,2,2,2,3,3,3,3,3,3,3,3,3,3)
a <-c(3,1,3,3,1,3,3,3,3,1,3,2,1,2,1,3,3,2,1,1,1,3,1,3,3,3,2,1,1,3)
b <-c(3,2,1,1,1,1,1,1,1,1,1,2,1,3,2,1,1,1,2...

altering identity column
Hi there,
I have a huge dataframe containing 70,000 observations.
I have filtered this dataframe (let it's name be "transformed_dataframe") as I wanted to select only those observations which are greater than or equal to 60,001 regarding the very first identity column.
So I have a transformed dataframe now including 1...

calculating the occurrences of distinct observations in the subsets of a dataframe
Hello everybody,
I have a data frame in R which is similar to the follows. Actually my real 'df' dataframe is much bigger than this one here but I really do not want to confuse anybody so that is why I try to simplify things as much as possible.
So here's the data frame.
id <-c(1,1,1,1,1,1,1,1,1,1,2,2,2,2,2,2,2,2,2,2,3,3,3,3,3,...

persuade tabulate function to count NAs in a data frame
Hi,
I'd like to ask you a question again. It is basically about data frames, NAs and tabulate function.
I have this data frame. I already used this in one of the previous questions of mine. It intentionally looks this simple, my real 'df' dataframe is much bigger actually and again, I am not willing to annoy anyone with huge databases... So,...
