# + signs appearing in console in R

To fix the issue you can do The + symbols are only a way to show that the current statement is conitnuation of the previous lines's statement. That's perfectly OK. There are a couple of other problems with your program which are stopping it from producing your intended result. If I have in fact, understood what you are trying to do, I have added a possible solution at the end. First, let me suggest the edits and the reason for them:
& should have been used instead of &&. & is the vectorized operator. So, upperright = a[,2] > 0 & a[,3] > 0 instead of upperright = a[,2] > 0 && a[,3] > 0. You are passing a value to the function so its definition should include the parameter calculation <- function (a) instead of calculation <- function (). upperright, upperleft, ... are vectors and you should check individual elements instead of the whole vector if (upperright[i]) instead of if (upperright). Problem with sum((a[i,1]-a[i-1,1])) at i==1, i-1 equals 0. If you are only counting, incrementing the count by 1 should be sufficient. The objects upperrightquadrant, upperleftquadrant, ... are in your function environment only. So, no need for <<-.
code :
``````set.seed(20)
x = matrix(rnorm(10,3,4),10,1)
y = matrix (rnorm(10,3,4),10,1)
time = matrix (1:10,10,1)
a = cbind (time,x,y)

colnames(a) = c("time","x","y")

upperright =  a[,2] > 0 & a[,3] > 0
upperleft =   a[,2] < 0 & a[,3] > 0
lowerright =  a[,2] > 0 & a[,3] < 0
lowerleft =   a[,2] < 0 & a[,3] < 0

calculation <- function (a) {
for (i in c(1:nrow(a))){
}

}
output = calculation(a)

print(a)        # input
print(output)   # output
``````
``````  for (i in c(1:nrow(a))){
if(i>1){
} else {
}
}
``````

## iconv() - Â appearing infront of £ signs from user input

help you fix your problem Works for me. If I set my OS X terminal window to ISO Latin 1 encoding, then
code :
``````\$ php -r 'print( iconv( "UTF-8", "ISO-8859-1//IGNORE//TRANSLIT", "Â£\n" ) );'
£

## Running a console app silently (suppress the console window from appearing)

By : user2983080
Date : March 29 2020, 07:55 AM
it helps some times This may be useful to other Windows programmers who need to suppress the shell prompt from appearing when running an executable program that by default launches a shell: (thanks to @Marc B and @ Joachim Pileborg )
Change the original line in the OP SystemX code from:
code :
`````` if(CreateProcess(NULL, cmd, NULL, NULL, FALSE, 0, NULL, NULL, &sj, &pj) == 0);
``````
`````` if(CreateProcess(NULL, cmd, NULL, NULL, FALSE, CREATE_NO_WINDOW, NULL, NULL, &sj, &pj) == 0);
``````

## console window no longer appearing on my Visual Studio Node Console Application

will be helpful for those in need If you run a command from the Package Manager Console from inside Visual Studio it seems to hijack the console window. Just exit and restart Visual Studio and it should work.
You may have to delete the npm-debug.log as well.

## some weird signs appearing on SQL SERVER Query output

By : Luca Bernardo Ciddio
Date : March 29 2020, 07:55 AM
wish helps you As noted in comments, use ELSE '' instead of ELSE ''''. The reason is that within a pair of single quotes, then '' tells SQL to escape a single quote into your output.
For instance, to show the output User's, you would need SELECT 'User''s'.
