This is my first post and this problem is really persisting, I am having this issue with my code where it breaks when I try to click my "Post Review" button.

QUESTION
The csv files are repeating the same information. I need updated information sent to the excel sheet from the three embedded sources. There is code that links the href from the base page to the product review pages. Also, when checking the output from spyder/anaconda python package, everything was coded right. So the problem has to be within the write function. Can anyone please help?
I've tried reformatting the code using a+ and w/w+, but nothing seems to work.
...ANSWER
Answered 2019-Mar-27 at 12:59You are looping through the reviews of each link, but OUTSIDE of your loop through the links. So essentially you're only holding on to the last iteration of those reviews. You need to loop through those reviews within each link. So essentially you need it to be a nested loop.
I also fixed the issue with the skipping lines in your csv by adding the parameter newline=''
QUESTION
I'm trying to create a program which will calculate a number based on a set of pre-set numbers. I've managed to do it, however, I need the printf part which displays the answer to be in the main() function rather than being in the function which does the calculation, and i'm not quite sure how to do it.
I've tried to just move the printf underneath main, but it says that the variables are not defined. I've also tried to put a main() after the equation calculation is done, but this doesn't work either.
The code below does what I want it to do, apart from the fact that print if is located in the equation function, rather than in the main, which is what i'm not quite sure on how to do.

QUESTION
I'm creating a program in C which will calculate something based on an equation with 4 sets of pre-set parameters. These pre-set parameters go into the main() function, however, I'm not entirely sure how to set them up. I'm assuming that once i've done it for one set of parameters, it'd be the same for the rest but just with different parameters.
Could someone point me in the right direction or give me some tips regarding this? I've looked up how to multiply two numbers together and then try to apply it to my case, but my numbers are pre-set and not input by the user, as well as there being more than just the main() function involved.
This is my code so far:
...ANSWER
Answered 2018-Oct-09 at 20:32From what I have understood is you want to create a program which will have one equation, with a fixed set of parameters and the value of those parameters may vary according to the user.
We can do this in 2 steps. 1. Create a function which will perform the calculation on the equation 2. Ask the user to enter the value
First we will see the general type
QUESTION
I am using ELKI 0.7.2 (master) for running DBSCAN with R* tree on a large data set. Afterwards, I need to store the tree persistently, so that it can be reloaded in memory when new data points are evaluated whether they are noise or not. To this end, I tried PersistentPageFileFactory and got the following error
...ANSWER
Answered 2018-Mar-14 at 09:51The disk deserialization code has been unused for years, and thus is likely broken.
I am even not sure if it ever fully supported reading back the index from disk standalone; I assume it was only implemented to simulate an on-disk index for benchmarking purposes (i.e., it will read and write the data from disk, but it probably cannot read an existing index).
This just is not a functionaly I needed, so I never worked on this code much beyond refactoring. And I have actually been trying to slowly remove much of this code (in particular ExternalizablePage) because I did not have the impression it is usable.
I have a rewritten version of the R-tree somewhere that is better suited for actual on-disk usage. But it is not finished, it does not support R*-tree re-insertions yet. So the code is not published yet (and may never get finished, unfortunately).
So you may need to rewrite large parts of that code to make it usable.
If you do so, please share your modifications on Github.
QUESTION
I read in some data via:
it.data <- read.csv("inputData/rstar.data.it.csv", header = T, sep = ",") then the second and fourth columns are inflation resp. interest:
inflation.it <- it.data[2]
and
interest.it <- it.data[4].
However, the trouble starts when I am trying to reform the data into a time-series object, because there are leading and trailing NA values in the columns. I have tried na.omit(), it.data[complete.cases(it.data),], na.contiguous, without luck. What happens now is that when I try to transform the data into a TS object,
inflation.ts.it <- ts(inflation.it, frequency = 4, interest.start)
I get very strange values which do not match with the original data.
Thanks.
PS. The data (I did not post everything, but just to get an idea):
...ANSWER
Answered 2018-May-25 at 11:50Assuming the dots are in the original CSV, you can fix it by specifying "." as na.string upon read-in.
QUESTION
I am working with 4 different time-series, but since all have different starting and ending dates, there are some 'NA' values. In order to work around this, I would like to cut out a few values at the beginning and end such that all variables end up with the same amount of observations.
My questions is: how does one achieve this? I have read that in the data preparation it is better to work in a zoo instead of a ts environment. Nevertheless, the data has already been prepared within a ts environment and has been saved as a .csv-file.
My standard way of reading in data:
...ANSWER
Answered 2018-May-18 at 13:02Even better would have been to store the time index in the file as well but since it seems this was not done we will have to add this knowledge externally in the code. Let us assume that it is a monthly series starting in January 1990. As the question states you are using a ts series environment convert it to a "ts" class object with the assumed starting time and frequency. Now we can use na.contiguous to remove the leading and trailing NAs and still keep track of the index.
