A quadratic model is a second-degree polynomial that takes the form of ‘y = a + bx + cx^2’. To graph a quadratic model in R Programming, you can use the ‘ggplot2’ package.

First, you need to create a data frame that contains the values of ‘x’ and ‘y’ for your quadratic model. You can do this using the ‘data.frame’ function.

Next, you can use ‘ggplot’ to create a scatterplot of the data and add a quadratic regression line using the ‘stat_smooth’ function with the ‘method’ argument set to ‘lm’.

R Programming offers a range of pre-existing datasets that are available for analysis and modeling. To access these datasets, you can employ the 'data' function followed by the dataset's name. Additionally, you can bring in datasets from external origins, like CSV files, by utilizing functions such as 'read.csv' or 'read.table'.

The mode of a variable is the value that occurs most frequently in a dataset. To find the mode of a variable in R Programming, you can use the 'Mode' function from the 'DescTools' package.

The ideal count of clusters is the number that most accurately portrays the inherent structure of the data. In R Programming, you can ascertain the optimal cluster count using methods like the elbow method or the silhouette method.

The elbow method involves plotting the within-cluster sum of squares (WCSS) against the number of clusters and selecting the number of clusters at the "elbow" of the curve.

The silhouette method involves calculating the silhouette score for each point in the dataset for a range of cluster sizes and selecting the number of clusters that maximize the average silhouette score.

The multivariate normal distribution is a generalization of the normal distribution to multiple dimensions. To fit a multivariate normal distribution in R Programming, you can use the `mvtnorm` package.

Principal Component Analysis (PCA) is a method used to decrease the dimensions of a dataset by mapping it onto a space with fewer dimensions. To choose the number of principal components in R Programming, you can use the scree plot or the cumulative proportion of variance method.

The scree plot involves plotting the eigenvalues of the principal components against their corresponding indices and selecting the number of principal components at the "elbow" of the curve.

The cumulative proportion of variance method involves calculating the proportion of variance explained by each principal component and selecting the number of principal components that explain a sufficiently large proportion of the total variance.

A time series object is a data structure that contains data with time stamps. Before running a smoothing analysis on a raw baseline in R Programming, it is important to convert the data into a time series object because time series analysis requires data to be in a specific format.

To convert a raw baseline to a time series object, you can use the `ts` function.

To get a count of a variable in R Programming, you can use the table function.

You can also use the count function from the ‘dplyr’ package.

In R Programming, there exist several approaches to rectify data issues, contingent upon the type of problem encountered. Here are some prevalent challenges along with their corresponding solutions:

__Missing values__: Missing values can be imputed using techniques such as mean imputation or regression imputation. You can use the ‘complete.cases’ function to identify rows with missing values, and the ‘na.omit’ function to remove them.__Outliers__: Outliers can be detected using techniques such as box plots or the Grubbs test. Outliers can be removed or transformed using techniques such as ‘winsorization’ or log transformation.__Inconsistent data__: Inconsistent data can be detected using techniques such as regular expressions or logical tests. Inconsistent data can be corrected using techniques such as string substitution or recoding.

**Code for: **Keyword Sentiment Analyzer

**Solution:**

```
```{r setup, include=FALSE}
library(tidyverse)
library(tidytext)
library(glue)
library(stringr)
```
## Defining the sentiment analyser function
```{r}
sentiment <- function(doc){
# tokenize
tokens <- data_frame(text = doc) %>% unnest_tokens(word, text)
# we will use the "bing" positive-negative words list
d <- get_sentiments("bing")
# checking if the tokens are there in the "bing" list or not
check <- tokens$word %in% d$word
# FALSE in the check vector means that this particular word is not their in the "bing" list
pn <- c() #vector for "positive" = positive word, "negative" = negative word, NA if word not in "bing" list
for (i in 1:length(check))
{if (check[i] == TRUE)
{pos <- match(tokens$word[i],d$word)
pn[i] <- d$sentiment[pos]}
}
# number of positive tokens
positive.count <- length(which(pn=="positive"))
# number of negative tokens
negative.count <- length(which(pn=="negative"))
# calculating final score
final.score <- positive.count - negative.count
return (final.score)
}
```
## Testing the function on a sample document
```{r}
sample <- "This dinner is WONDERFUL"
sentiment(sample)
```
```
