R help - Apr 2008 - how to modify the histogram's frequencies

Hi:


I have been trying to figure out a simple way to plot an histogram whose
frequencies are modified by a factor (associated with each value).


Actually what I did was plotting each value with its modified
frequency(using plot($values, $frequency, type="h")), but it doesnt
take
into account the probability distribution(which is necessary).


It will be very helpful from you any approach to solve this problem.

thank you,

best

Hi:

 

 

I have been trying to figure out a simple way to plot an histogram whose

frequencies are modified by a factor (associated with each value).

 

 

Actually what I did was plotting each value with its modified

frequency(using plot($values, $frequency, type="h")), but it doesnt
take

into account the probability distribution(which is necessary).

 

I think you should be able to:

 

newvalue=rep($value,$frequency)

hist(new,value,freq=F)

Hi Sarah:

Thank you very much, but my problem remains. What I want is not duplicate
the sample, but be able to divide each frequency for a factor(specific for
each value).For example:

Values           1      2     3    4     5
Frequency      10   34   56   67   98
Factor           105   50   60  150  200

Actually Im plotting: plot(Values, Frequency/Factor, type="b"). But I
dont
know how to visualize the probability distribution. On the hand  to modify
the "hist" function to include this Factor seems to be a daunting
task.

any other advise will be welcome

thank you

m.
